Adam Savage's One Day Builds: Special Effects Syringe!
Вставка
- Опубліковано 27 сер 2024
- This may not be for a squeamish! Adam takes a vintage medical syringe and turns it into a practical effects prop! Using telescoping brass tubing and a custom machined front sleeve and plunger, this prop creates the convincing illusion of a needle injection that would be suitable for theater or film!

I had always wondered how this special effect was done.
Tooth extractor next 😱
Hey Adam
Use some very porous sponge foam of desired colour sted of liquid... it should work i guess...
& If you want the liquid then use a insulin shot kind of injection hidden inside the plunger tube ... So that when you inject the prop then liquid will push back that hidden injection through the hole inside the plunger like reverse hydraulic
(You'll need a small hole to let the air escape from the end toward thumb so the hidden injection's rear end will have no resistance when the liquid start filling in... You'll still have air bubbles thanks to the position of hole you made for the liquid to disappear is in center... So it'll look nice)
@@mikeuk666 say "ahhhhhh"...
I was attracted to the episode because of my opiate addiction. I was always fascinated they made them in the 1800s with the precision. Given the size of the needles back then, I think most people would be afraid of them.
I love the off-the-wall esoteric quality of builds like these. No reason, just something Adam wants to do. These will always be my favorite. Also wondering if a graphite infused o-ring, if they even make that sort of thing, would make the operation a little smoother.
This almost feels like a "Spur of the moment" build rather than a planned One Day Build. Love it.
I certainly know "Because I want to" is responsible for 90% of _my_ makery. 😁
I also love his enthusiasm as he goes. And, as he doesn't complete his sentences while he's working out a problem. I think that rings true with most of us who make things on the fly.
@@woodandwheelz Or when he does something just out of camera view because he is so into what he's building.
It'd be nice if they gave a warning for things that wound up not working out (like flashing "nope, that's not gonna happen" on the screen when he says he's brainstorming in the beginning) I was watching that whole video anxiously awaiting how he was gonna make the fluid disappear lol
i never went as far as anything beyond high school prop making, but my favorite was an axe i made that was covered and dripping in "blood" i used a little pump i imbedded in the handle with a reservoir of theater blood. hallow aluminum handle panted to look wooden with micro tubes going up and running across the bottom of the "blade". small holes let the axe drip it was so real looking they thought that one of the actors got hurt. i really wish i would have pursued theater prop making.
It's never too late, my friend.
It's never too late, my profession didn't exist when I was in high school
In high school? That's amazing!
Very impressive, carbonitedreamer! I've seen countless theater and screen props, but never one that actually dripped blood (or any liquid, for that matter!). And it's definitely not too late, by any means!
It’s never too late. I was attracted to this because of my opiate addiction. Wanted to actually see what connections Adam had to addiction if any and his thoughts. I was always fascinated that they made syringes in the 1800s. And given the size of the needles, I was scared too, trust me.
PS, Once I felt what it does, that fear melted quick.
The most horrifying bit of this was the sound of its operation! I think the disappearing fluid thing could probably be done with a plunger shaped like the original, but hollow. Have a small hole in it, and then as you depress it the fluid would be forced from the main body into the body of the plunger, seeming to disappear
yeah, I thought that was what he was going to do
Maybe make the plunger a dark color as well to hide the liquid going into it.
You could also inject the fluid into a person, effectively ‘hiding’ it.
@@GarryAndrews_ lol
I was thinking that as well, perhaps will a bladder/balloon type arrangement that would allow create a vacuum and allow/force the liquid to move at any orientation of the syringe.
you haven't lived if you've never pretended that your mechanical pencil was a syringe
And make the "FSSSHHH" noise if you're pretending to be Dr. McCoy.
What about telling those that are ignorant that you now have are being poisoned by lead? Oh many a happy childhood memory.
@@asgdhgsfhrfgfd1170 I don’t believe actual lead was ever used in pencils. Graphite used to be called ‘black lead’ before we knew it was carbon.
@@asgdhgsfhrfgfd1170 That was the joke, that I was alluding to above.
@@gorillaau I was going to say "But there's always one smart-aleck in the group who'll say 'y'know pencil lead isn't really lead,'" but he seems to have already turned up. 😁
This is therapeutic for me because I have a phobia of needles, especially syringes. Knowing they’re fake in movies still bothers me, but seeing how they work helps tremendously.
Oh, good!
Oh! Hard same! I haaaaaaaaate needles and it took everything in my discipline to get vaccinated, but this is fascinating!
Same here! I've fainted getting injections before and seeing them used to make me feel sick but now I pretend they're all like movie props 😂
I dodged this video a couple times before I realized it was Adam haha, needles are the worst.
@@ianwhelan-miller90 I used to hate needles just like you two did, when I was ~13 I got Type 1 diabetes and that phobia became impractical, and boom, it was gone about a week later.
I wouldn't worry on that phobia, in an emergency it will be gone like a puddle on a warm day.
So, when shall we expect to see the "holding one end of a piece of metal with bare fingers and heating up the other with a blow torch" demerit badge?
In the time that it took my mind to form the thought of "Wait, metal is very thermally-conductive", Adam rediscovered that on his own.
Not a blow torch, but I have lost count of the number of times I burnt my fingers soldering very tiny things. Anything with alligator clips just butchers 30 gauge wire- but fingers + some flat surface (like a table) does the job pretty well. If you're steady enough to solder between your fingers, and fast enough the heat doesn't travel.
I have also been in a situation where I forgot that metal conducts heat. I've known of a few other people forgetting this, too. Certainly a badge I'd be earning
I used a variety of syringes during my synthetic organic chemistry career, including that glass gas-tight syringe you modified in this video. Definitely an underappreciated one in the labs because they're a bit finicky to use but super handy to transfer relatively large volumes of air-sensitive liquids when cannula isn't an option.
I'd actually think that a second O-ring near the back of the large section of the plunger might be sufficient to keep the aluminum from contacting the glass; not as a seal, just as a bearing surface. Might still need something farther down the shaft, but it might also be just right.
I think you’re right. I was looking to see if anyone had made this comment already when I found your. It seems like the real medical syringes I’ve seen had two o rings, but 8 could be remembering wrong.
I’m a sucker for ambiguous phrases like, “Starting to look like a thing.” They are among my favorite requirements in any process.
I'll never get over the practicality of Adam's tattoo
Not only does it speak to who he truly is as a person, it's also incredibly handy for making rough measurements on the fly
Genius really, but I espect no less from the Savage
Hardly the first person to have a ruler/measuring tattoo...
@@AdamByers001 yeah man, a good bit is a good bit :)
I am so Proud of Adam, he has been working hard on his Clint Eastwood impression and it is paying off 20:42
It would be really interesting to see a walk through of Adam's pocket knife collection!
Mental note.
I second this motion. That knife at 7:49 - a sheepsfoot with a thumbhole. That's my favorite style of pocketknife.
@@danielbaxter33 for anyone curious, that seems to be an Urban EDC F5.5
@@crenshawyeo yes, it definitely is
Is this creepy? Yes. Am I very interested also yes. Am I surprised Adam Savage has a collection of old timey syringes not in the slightest I love this!
Yeah, I don't love needles either!! SO thanks for this video! ;-) Early last year I had the unfortunate pleasure of getting Covid [Delta] and ended up in hospital and, a couple of days later, in the ICU where they put in all sorts of needles in the arms and a catheter in the you-know-where!! So for eight days I was fed by tube, had blood taken from the tubes, fed water and medicine through the tubes, and excreted through a tube into a bag. Oh JOY!! Then out of the ICU and into a ward minus a few tubes, but I cannot tell you the relief and joy I felt when they took out the catheter and the last tube from my wrist [ok, it fell out!]! I cannot express how thankful I am to all of the nurses and doctors who took care of me at Uppsala hospital - I don't know how many as I lost count - their absolute professionalism and dedication [12 hour shifts for six days with four days off] was so amazing to witness. I don't thank them for all the needles though!! Oh the terror, the terror, the terror ...
The way it presses in the skin as the needle slides back is so disturbing and looks so good!
Right?!
This was super enjoyable to watch for me. More of an impromptu build, no hard plans, no crazy measuring other than what needed it. Really enjoyed the plunger handle. Turned out great!
Adam never ceases to amaze me with his skill, imagination and enthusiasm.
Adam is the coolest. Just the fact that he has an antique syringe collection... and showing that syringe at a dinner party is exactly what I would do!
I haven't had an urge this strong to make a matching build of my own. This would be a perfect addition to a vampire hunter set I'm planning on creating. Great vid!
We hope you share on social and tag us when you do!
I too have always been morbidly fascinated by prop syringes. I’ve worked with a few of them over the years, and they’re always so fascinating and fun to mess around with
I became a type1 diabetic as a 3 year old in 1976, so I remember glass syringes with screw-on needles only too well. As a particularly small child the syringes were getting on for the size of my arm, I can only sympathize with my mother having to insert a comparatively Massive needle into tiny me as I can still remember how much I'd cry!
My favorite part of these builds is that he just does them, he has not prepared a plan or anyhting, he is just doing it because he wants to. Adam is the best.
There is this optical ASMR type of quality to just watch Adam think. It relaxes me in the most difficult situations
The glass glowing at around 15 minutes in when Adam was drilling it out with the helix bit was so cool.
Love seeing Adam giddy.
Thanks for the flashback to my first 11 stitches back in 1984.. lol.. loved it when they had to clean the wound with the wire brush too 😆 ( it was stiff plastic, but might as well been a wire brush..lol )
Gah!
I wish this video was around when I had to figure out how to make one for a film. Same road I took in this video, love it.
I get so many good products watching these videos. Adam always plugs decent products and manufacturers
My dad was a dentist and when I was very young, maybe 6 years old (over 60 years now), he got from a pharmacy rep, a fake syringe with a spring loaded retractable needle. It had a cylinder of red plastic that would hide inside a larger opaque cylinder in the tube. When pulled back, you could see an empty syringe. When you pushed the plunger in and released the red inner cylinder (a simple pressure fit at the thumb end of the plunger) and pulled back on the plunger, the red bit was left exposed in the tube and it was a pretty convincing blood draw. It was AWESOME! I took it to first grade show and tell (without my parents permission I'm sure) and the teacher confiscated it. But I learned some magic there...
I remember using the exact glass plunger syringes early in my career. They were specifically designed for the siting of epidurals, and used to injected air, designed to be a low pressure system. The plungers were designed to leak around the barrel if the pressure got too high. I think that may be why a firm seal with the new plunger proved difficult.
Adam, you are the geek we all strive to be. Follow your dreams and take us with you
Darn, I was really hoping we'd see how to do the disappearing fluid trick! (The spring-loaded needle is simple enough to suss out, after all.)
You just need a way to hide the liquid, for instance in the plunger. Instead of using allthread, use a thin-ish tube and make a hole for the liquid to escape upwards into the plunger stem and pusher, if needed. The comically huge plunger also holds a fair amount of liquid.
Don't worry; it'll likely end up another video!
I wonder if it could work in reverse, as if you were drawing blood?
From what Adam was doing with the glass plunger, it looks like all you need is a space into which the liquid can flow.
@@tested yes please!
Did Sweeney Todd's squirting razor once, but I expect everybody's done one of those. Same with the bleeding garrot from Deathtrap - icky and triggering but also a pretty common item. The trouble with your trick syringe (if you don't mind a little critique) is that needles don't have steps in them, and as you're not injecting anything you don't need a needle at all. Use a blunt piece of piano wire and make the retraction/travel entirely in the metal attachment collar and the metal sleeve behind it. The hollow plunger head can give you even a little bit more travel, and still give you the 'disappearing liquid' effect. Vent it on the back of the plunger and put in only as much fluid as will disappear, and you could seal the whole thing permanently.
Hmmm. I thought you would be able to pull up liquid and have it seemingly disappear when the piston would be pushed all the way in.... that would be a nice effect... use the retractable needle to pick up liquid (maybe have a one-way thing in there, a small iron ball that would not let it flow out or be pressed out), then when the piston is pushed, redirect the liquid somehow or just let the air escape from the piston end so the liquid can go into the space in there... I would definitely go full circle with the illusion there :) Love what you do Adam!!
I love these videos. Being able to see your creativity is the only way anyone can get me to watch a 30 min. video on making a syringe
Now I'm really curious as to how Adam planned to do the disappearing fluid trick. Maybe run it up the inside of that threaded rod and out a tube to somewhere?
Needle is sealed, the plunger is hollow, when you push the plunger the fluid just goes inside the plunger head and the threaded tube
Stay tuned; he's been thinking about it.
The trick is you need a hole in the end of the plunger to allow air to pass through as the plunger is plunged/retracted Otherwise the liquid has to compress the air. I'm not sure if you can avoid the liquid squirting out of that hole by having a much larger volume in the plunger as compared to the volume of liquid.
You would have to be pointing the syringe downward as you use it to prevent the liquid from just dripping out via gravity, but you can put your thumb over the hole before you use it so you can orient it however you like without issue.
@@tested I'd originally thought something like a water hammer arrestor, but looking forward to finding out
@@tested 2 of "1 way valve" sort of system on the hollow but "both sides closed" plunger's head,
one at 12ish o'clock lets liquid in the cavety,
one at 6ish o'clock in reverse lets it out......
plungers head must be hollow and able to contain the required liquid amount (or bit more), till that liquid is no longer visible.....
You could hide some of the liquid on syringe's head as well (so the plunger does not get to the actual end of the syringe, solving any troubles about escaping fluid from inside the plunger)
-or make the syringe's head the conteiner of that liquid it self (that would solve the visble valves holes on the plunger problem, but someone could thing of them as screws for the plunger head as well)
1 way valves do exist ???? XD
you could also make an airvent through the plunger's tube / rod back to where your finger is pushing it. you can just block / ublock that vent's hole with your finger any time you operate it to let air out / in as nececery.
Or make an colored (as nececery) tranparent acrylic tube that fits infront of the plunger (beeing it the liguid),
wich hides in the syrinnge's head when it moves forward and comes out when the plunger retracts. Giving a shot / taking blood....
I've put together & did the soldering of 3 different lightsabers. One of them I actually created some attachments for (knobs, shaped covers, ect.) & am still making some! Not all of them came out the best looking, but I'm getting better & the better I get the funner it gets!
As someone who hates needles. Thanks for helping me overcome my fear of them! a bit. maybe.
Looks great! You could even UP the squeamish factor exponentially by using the original glass plunger (presuming it is hollow), and applying a little Boyles Law and hydraulics principle. Use the compression of the plunger to force the "blood", super serum, or Zombie juice into the plunger from the syringe...as long as you watched your level rise in the plunger you could give the actual appearance of the fluid being injected (ala magicians milk in a paper cone). You could reuse the effect over and over and never lose your fluid.
13:57 Adam flexing maker muscles 💪💪
I’m always just so amazed at the creative process and what Mr.Savage creates. Endlessly entertaining
What this needs is some of that green glowing ooze from the classic horror flick Re-animator. 👍❤️
Looks great! I would make the plunger slightly longer so there is still a small gap between the handle of the plunger and the glass of the syringe when the plunger is pushed all the way down.
This has to be one of my favorite Adam-builds. 😎
25:50
When you catch yourself LAUGHING OUT LOUD with someone on their month old video.....like he's right there with you!
That's "chemistry" guys! Pure and Real!
What a great Maker video! This syringe/needle is a work of art in the world of props!
I wonder how much this would sell for on ebay? For a charitable contribution of course!
Less than a minute in, and I'm greeted with the lovely sentence, "I have a beautiful collection of antique syringes."
Class.
i generally don't have a phobia of things, but one thing that always freaked me out was the needle pit in the SAW movies, even watching the behind the scenes it still gives me the heebie jeebies
love the work Adam!
*edit spelling
Beautiful build. We still use ground glass syringes for spinal taps, because the ground glass plunger to ground glass syringe cylinder fitment can be made so closely that the syringe can actually bounce on just the air pressure in the syringe, or the fluid pressure in the spinal canal, with a tiny bit of resistance. The seal is actually made from the water's surface tension between the two ground glass surfaces. I think this worked against you in this setting, as the inside of the syringe is not smooth, which makes an imperfect seal against the O-ring, preventing it from mating and sliding as expected.
That was Savage Adam!
Damn it brings me so much joy watching Adam working on stuff like this. Brings back a lot of good memories from my childhood :)
What a wonderful performance by Jamie.
in Tech school my second class was making props - I made a old weathered cheese cutting pallet ( the kind with a handle) and my teacher hadn't seen it much . When leaving class I asked him what he thought about it - and in the same breath I BOPPED him on top of his head !!!!😂
The look on his face was Priceless !!! It took him about 1 full second to realize it was made from FOAM , and completely harmless .
Adam savage!!! I have the perfect one day build for you!!! With assassins creed coming back into popularity making a hidden blade would bring you TONS of views
That laugh at the end when you almost stuck yourself and then realized it could use some more oil. lol You are the best Adam.
I always think, how is this done. Thanks, Adam. You show me the way.
I have needed FX syringes for more than one show over the years and thankfully we were able to just hide the actual act of the actor being injected, but just yesterday I was watching a movie where someone was injected with one and I said to myself I really need to revisit this and see if I can make one. And then this video came up!!!!!! I'd like to see how the liquid works in this.
I have become the go to person amongst my theatre friends for gore/blood related props. The most gruesome prop I've made to date were Scotty's intestines for Evil Dead the Musical. First time I made them I used plastic shopping bags and pantyhose to soak up the stage blood and make them squishy. The second time I still used plastic shopping bags, but I covered them in layers of liquid latex to make them more slimy.
Long marshmallows covered in blood make good guts
I think Adam wimped out and didn't make the liquid disappear part.
I love the mini table saw
The disappearing liquid solution was right in your hands after carving the hole in the end of the glass plunger. Make a tiny hole in the other end of the plunger, or if it's open ended, make a plug for it with a small vent hole. Apply paint to the inside of the plunger and you're done. The hollow plunger can move back and forth to "inject" or "draw out" fluids but it's just flowing in and out of the plunger.
I love this guy! I have decided I am going to binge his stuff for days
Yay! I was wondering when we would see the return of that mini cut off saw. Excellent!.
i love how Adam sometimes think we can hear his thoughts and replies as such, or simply continues the conversation from inside to outside his head,
and dues, us only hearing half of the conversation LOL
Great video Thank you for sharing. Keep em coming, everyone keep yourselves and love ones safe and healthy.
Good art is art that makes you feel a strong emotion. It doesn't have to be a good emotion.
We used to do special effects like every teen/young adult in the 80s-early 90's did and to date the most unnerving prop was the simple, "Dulled Razorblade".
You just dull a single sided blade and then lick the "keen" edge with the tip of your tongue and/or roll it around in your mouth in a feat of "bravery".
Always a croud pleaser ;)
Props to Tom Savini's Bizarro which all our good effects spawned from !
These old time looking syringes would make a good prop for one of the various medicines the Hunters use in the video game Hunt Showdown. The tarnished brass combined with the bright colored fluids really stand out.
Love every project you've ever work on man. A true idol of mine. Love my tinkering as much as you do. Lol
What a coincidence! I just had to make one of these for a movie, retractable with fluid and all in a 5cc syringe. Really fun to see Adam go through the same thought process and getting to more or less the same solutions!
Haunted house artist here, and a few classic squeamish props include:
-Amputation tables (table w/hole for actors leg/torso/rest of body, dressed with costume/fake limbs to create the illusion of a live amputation)
-stretching racks (similar to amputation table, but with two actors for upper and lower body or simply pneumatic lower body pieces, with silicone goo attaching the connecting torso viscera for that extra squelchy/stretchy look
-spark fences! (chain link fence hooked to one end of a car battery charger, other terminal attached via long hidden cable to a chainsaw bar/knife; the rustier the fence, the better!)
-Sweeney Todd barber capes; saw one in a promo that had a sliceable flesh piece-- the safety band behind things like this are ALWAYS important to remember!!!
-there's a product called cockroach crunch which is spead on the floor of bug-themed rooms to create the feeling of stepping on insects i rather enjoy
-guillotines with drop-away neck holes
There's also some great uses of peppers ghost combined with pneumatics to create the illusion of, say, a piston smashing someone's head in (and then customers having to move past the same piston, which of course moves a little bit) or the like, where an actor plays the lead up to the smash, and then the strobe lights conceal the switch to a peppers ghost scene of a body in the same costume all gored up.
Much of the haunted house industry is a bunch of engineers recreating effects from magic tricks, hollywood productions, and stage shows in low-budget, highly-repeatable forms. Some of these require concealment with strategic lighting, some just need repair/refreshing (see: sil-blood) from night to night, but if you're feeling extra excited about maker-made storytelling pieces that really make you squirm, i cant think of a better place to look!
I've never built one, but I LOVE effects props like popping eyeballs.
The spring has sprung 😂 thank you for entertaining and teaching us builds!
As someone who works in vascular interventional radiology I love needles. From micro puncture, single wall, acustick, trocar and so on, I could handle needles all day long. Nice build as always Adam.
Interesting... Only needle that didn't trigger my need to look away. Thank you
I love what you do Adam please never stop
Hi, Adam.
You mentioned the "double helix cut hardened steel bit." Wondering: do you (or anyone we know) have a LIST of "highly specialized tools and what they're perfect for"?
(I'm envisioning a 2 column spreadsheet, so if (years from now) I want to look up "ideal for cutting a round hole in glass" or "drills square holes" or "makes the perfect pizza" or whatever, I can do a search based on the JOB and find the name of THE tool.
Anyone out there maintain such a list?
Just a thought and thanks in advance!
great idea
We print and laminate charts available online for future reference. All based on specific materials. I have never seen a single list, I imagine it would be a long one lol.
This sounds like the makings of a huge list which should be printed yearly and become a maker's directory.Or as we makers call it. The Directory. 😍
ua-cam.com/video/I7BbrjoftJA/v-deo.html
AvE used to make good videos.
To cut glass that would have been a carbide bit (burr). Pretty common tool, but Adam often calls things by the wrong name, so it's tricky to know what to look for.
My favourite gross prop is a pro wrestler, Jon Moxley, who snipped the teeth off then filed smooth a sawzall blade then let an opponent press it, while running, to his forehead. It looks gruesome but, because the blood already there is mixed with sweat, the completely blunt (like, to the level of a butter knife) blade looked like it was cutting into him when it was just pushing blood and sweat around.
I think this is quite neat. Watching you complete this build while having the biggest sleep deprivation i have ever had was quite a rollercoaster of different experessions. I like any kind of physical objects that move, make a sound and you can fiddle with. They become even better when you get to make them :)
Glad to see the humble t-shirt is part of the working surfaces
Inch-and-a-half "needle!" Wow. I'm not a medical professional, but I regularly inject myself, intra-muscularly, with a medicine using a 23 gauge one-inch needle. Yours really gets into "scary" territory, especially with the gauge of the "needle" you use.
Every day, Savage gets closer and closer to completing the transformation to Doc Brown.
The stitches/Novocaine reenactment made me laugh so much! "Veterinarian needles" 😂😂😂
That first shot of the brass “going into” Adam’s arm absolutely made my skin crawl
This looks like it came straight out of Bioshock! Love it
this was such a fun build! there's something so neat and satisfying about the glass vintage syringes
This was very enjoyable, greetings from the Netherlands!
what a brilliant thing . Adam your a genius . well done and thank you for the video .
I would like to see more on plating, wood, plastic, and other metals.
Thanks love the channel
Suggestion for the fluid trick: use the original glass plunger that you Dremel'ed a hole in the beginning. Coat the inside of it using paint color that matches frosted glass. Frost the outside of it heavier too for good measure.
Now drill a hole in the backend of the plunger as well. Fill the syringe with "medicine" of your choosing, then when you push the plunger in, the fluid will be able to go into the plunger and the air can escape out the other hole you drilled.
You could put a check valve in the front side of the plunger hidden in a rubber gasket (like modern syringes have) so that the fluid can't come back out of the plunger once it goes in.
You could take it a step further, forego the check valve, and pre-fill the plunger with a dye. Then when you push the first liquid in it mixes with the dye inside and when you pull the plunger back out, the dyed liquid refills the syringe but there's a vacuum so you cant really tell which way the fluid is filling the chamber from
Never made any props myself however I do like the prop knife that they used in Dexter for the close up cuts for his blood slides. I just think it was a pretty neat trick because of how close up the shots always were it adds an extra challenge as to where to hide the mechanics.
That small bench vise looks amazing
I think the Spring-Retractable Needle would be a super cool way to make spring loaded pistons/actuators for miniature model making, I'm going to have to give this a try.
-Thanks Adam!
Nice project. seems like a lots of fun to make. I am happy to see that a slipping drill at 14:32 also happens to the best lol. I think if you would make the plunge hollow instead of the needle, you could actual create the illusion of disappearing fluid by let the fluid go inside the plunge when pushing it in to the syringe.
Cool point to note about glass syringes (if you don't cover it already in the video!) is that the plunger should spin freely inside the syringe body, it should be perfectly aligned and the tiny amount of air around it acts as an almost frictionless (or at least massively reduced friction) aerodynamic bearing. Looks really cool as it spins!
Steve Mould's video on aerodynamic bearings covers this beautifully btw if you'd like to see it!
Totally love this! I'm just putting together props for a production Sweeney Todd, this time set in a horrific nightmarish abandoned hospital, I've been wondering how to make a trick syringe. This is totally awesome!
Excellent timing!
But first, let's clean it. *Pulls out dirtiest rag in the shop to wipe it down* hahaha. I love this channel. Gets everyone in the mood to be a maker!
I was in the Royal Army Medical Corps in he early 1970s. Although most syringes were the single use plastic kind, we were still using some of the old glass syringes. Although the smaller syringes used stainless steel plungers, the large ones (10 ml and upwards) invariably had the ground glass plungers like the one you replaced. I think this was a weight issue... you really don't want a heavy plunger thumping home when receiving an intravenous injection (that's why the glass plungers are hollow)!
Although ground glass isn't opaque, perhaps it could be without being too obvious. That way, the fluid could go into the plunger invisibly if there was a small aperture in the base of the plunger. It would be a matter of equalising (I'm a Brit so I spell it with an 'S', okay?) the pressure between the space within the plunger and the chamber of the syringe. Pressing the plunger home would force the liquid into the plunger but also you could mimic taking a blood sample because withdrawing the plunger would suck the fluid back into the chamber. It wouldn't be obvious that the liquid was coming from the plunger rather than a vein.
It's just a thought and I haven't tested the theory but it might be something you could think about. Your build looks convincing enough to those unfamiliar with old syringes but those who are would be wondering why the syringe has a piston that looks like it came out of an internal combustion engine.
this came out fantastic! 👏😎
Just a note on syringes, having to use them everyday for my diabetic cat. Function implies form, syringes are very mechanical and made for very specific purposes. Everything from the gauge of the needle to the length of the chamber and the units all imply the intended use of the syringe.
Watching Adam making decisions is exactly like watching me while making cosplays.
I'll be thinking about this build at work tomorrow. We use a lot of syringes in the Operating Theatre (OR for US folks). 😀
