Not a bad idea... Except only if the 'uncrushing' does not occur immediately and restore its shape in a split second. Otherwise a one or two vehicle accident can end up involving few hundred vehicles.
Normally that sort of collapse dynamics would require slow motion. The same structure can have different buckling eigenshapes at different loading velocities. Normally, unless you seed one eigenshape (as they did in the pen, with a hexagonal die at one end to start an n=6 collapse, or in a vehicle crumple zone where n=2 is the norm) you usually only end up with the lowest-energy eigenshape (n=1, as in the hydraulic press) unless you're impacting at very high velocities.
The best thing about TAL is that he shows us very excited stuff that we ourselves would go nuts seeing in real person. Lots of other channels would just rush over showing off the pen, but oh I so do like he takes his time with it, cause I would be playing with that pen ALL. DAY.
And he's got a great sense of timing too. The way he edits the video makes it feel a lot shorter and more video-like, as opposed to the more commonly filmed lectures video with the random silent pauses in between
Yes, Noah Deledda has made some amazing artworks that led to the inspiration of this pen he designed. I purchased one a while back and love it. I've yet to remove the red cap from the cartridge and actually write something with it though!
I owned one and it dented permanently like he showed on a hot day when I held it with too much pressure; but to be fair I used it often for a couple of months
@@moistbread8531 try removing the film and soak it in some warm water for a short time,it may come back to it original shape.but don't use it until it cools down or it could be further deformed.
@@flordelphinta I bought 5 of them. One is dedicated to being used ruthlessly. I carry it around in my pocket with my phone and keys. I work at a library and I've used it non stop for at least a month. It's a little dinged, but functions pretty much the same. People love it. It grabs attention and starts interesting conversations.
At 4:47 where we see it takes progressively more force to cause each later of deformation, I don't think this has anything to do with the deforming material but likely has more to do with needing to increase pressure on the pen's spring to continue to compress it.
Of course when you are further and further compressing an object within its elastic deformation, it will get harder and harder. If you want to squish a basketball by a few mm, you can do that with our fingers, a couple CM you may be able to do with your body weight, if you want to compress it 50% you're gonna need more than a ton.
I received my crushmetric pen in the mail a few days ago, and it is so fun to fidget with and take apart. Everyone I show it to is fascinated by it. The only problem is how relatively delicate that metallic sleeve is
Ive Seen the ads and accounts that copy it but by what i saw it should be absolutely possible to reinforce it with carbon fibers or anything like that while keeping the ability to crumble and uncrumble
5:05 I mean, it's still an elastic deformation, but they added a toggling effect by adding unstable equilibrium points on every section. So it looks like a plastic deformation for the part, but the material doesn't yield.
I'm pretty sure I remember seeing either part of a documentary or the entire thing was about this guy who would crumple cans artistically. He would essentially do what you did to the pipe to a soda can by hand and he would make art out of it. Might have been on PBS
Finally, one I have prior knowledge of! This was actually used on 1980s sports cars. If you've ever seen a 1980s Porsche with a weird corrugation behind the bumpers, it was designed to prevent minor impacts from damaging expensive internal pieces and paneling. There wasn't much actual room, but it put a maximum force threshold on the car during an accident, which saved a lot of those cars from otherwise expensive repair work. Of course, now corporations (wrongly) make the assumption that people will actually know how to drive cars worth $100K or more, but the working principle still has its use!
You’re a genuine person. Thank you so much for your videos. Even though you get paid a lot to do this, you can tell that you really do like teaching with the insane amount of effort and just seem really cool overall. You may not ever even see this, but I really appreciate you.
Mercedes Benz invented the front and rear crumple zone, but unlike most manufacturers (especially American) they recognized the life-saving potential and chose not to patent the idea, but instead, actively shared it with other manufacturers and designers. If only other companies and industries (i.e. drug companies ) had this kind of ethical approach to invention.
gotta be honest finding out it wasnt a metallic substance that snapped into that and it was just plastic sliding into a shape was a bit disappointing, but it still looks cool!
4:07 - 4:15 Was trippy with how the tube went flying to the top left of the screen and then you suddenly brought it out from the bottom right of the screen with the smooth transition.
Not a big deal. 35 years ago, I left my little Coleman cooler on the ground at a construction site. A front end loader ran over it smashing half of it down to around 1 inch high. I threw it in a trash pile near by. Over the weeks I noticed it reexpanding. A month or so later it was back to its full size with almost no signs of any crushing.
Finally someone took one apart and showed us the workings of this pen. I thought there was some sort of consortium regarding this pen and it being taken apart,as I could not find a single video of it and how it works. Thank you so much.
i saw this product from the creator in instagram. I thought it was the most artistic pen I've seen. The creator of this pen does aluminum sculptures which inspired him to make this pen.
I used that crinkling kids toy as the crush zone for a model car around five or six years ago in a high school physics class in a competition to make a scale car that would save an egg from a head on collision. Worked incredible! We got full score and outdid every other group. So cool to see a video on it now!
Brilliant videos. It's great how he describes how things are so cool when it's his enthusiasm and style that are so cool. Never stop making these videos please, they're so cool!
This reminds me is the roswell crash and reports from town members claiming he found metal scraps they were able to crumble up and then it would reform to its original shape.
Interesting fact. This is how flies like greenbottles and bluebottles are able to beat their wings so fast, so effortlessly. Their exoskeleton deforms elastically on the downstroke of the wing beat and when it pops back into its normal shape it flicks the wing back up. Well, it's more like those toys you turn inside out and wait for them to pop back up several feet or so.
after i saw the tiktok about the crushmetric pen, i thought "i have to get one of these." got my boss one of these for their birthday! they absolutely loved it.
The earths upper crust is sort of like this. It can bend and flex to a certain extent, but when forces get too strong, the elastic limit of the rocks are overcome and the rocks break along faults
"Instead of crumple zones our car has reinforced plating to ensure negligible structural damage. Your heirs will receive a valuable piece of capital equipment in good working order."
Why does it always start from the same end though ? The compression force should be equal everywhere normally. Even with the hydraulic press it seems to always start from the top.
because you give force from the top. if you give it force from the bottom, it crushes itself from the bottom. like in a car crash. the back doesnt just crash, the front does because it recieved most of the force.
@@EGS3586 No. In a car crash the only force applied is on the front. In these compression examples the force should be equally spead along the cylinder and the cylinder shouln't "notice" which side of the machine is "active".
@@EGS3586 Re-read physics 101 pls, Newton's laws? In simple form, when talking about forces on an object at rest, "for every action, there is an equal and opposite reaction". Your talk about "force from the top" is much misguided. Force from the top just implies equal and opposite force from bottom. Even in a car crash, the forces are massive on both front and back side of the member that crumples. (Though unequal because it's decelerating.) The hood and chassis crumples more in front primarily because it's *not uniform strength* along its length! (Unlike the pen sleeve.) Front is weaker due to all the angles and layout of structural metal, stringers and stuff, but crumpling does not apriori proceed from front to back like you imply. At 1:55 you see the hood fold in the middle, because that's the next weakest spot in its construction, not because test harness "gave it force" in the middle.
@@EvilCherry3 True in the second part of your comment. Yet in a car crash you're slightly off target; on every member the force on the front is opposed by reaction force on the back, that's what crushes them... In deep space, when you have a rocket engine thrusting it forward, you could say it is the "only force" applied. Thus no crushing happens. Your question is interesting though. I imagine that perhaps there's an initial condition involved, like, the switch end of the plastic base is maybe slightly less round (maybe notched somewhere?) than the writing end. That would create this effect of sleeve starting to deform from there consistently, methinks...
The brilliance of the crumple zones is that deceleration is what kills you first. Try clapping your hands with even the smallest paper cup in your hand. There is no clap. Makes a minor front crash (thankfully) kind of boring compared to a 70s car. I saw that curious diamond pattern on a very heavy (30lb?) roll of very thin craft paper, from Uline I think, when it landed on a work table.

A short video on differences in liquid reactivity during heating processes would be cool. I.e boiling water in the microwave vs stove and watching the volatile reaction with a tea bag because of the dissovled gas differences.
I got this pen from kickstarter for my son to have a cool pen for his first year of school. Of course it took him a week to "permanently deform" that metallic foil part :)
I got my set last week! I bought several when it was still being crowd funded. I completely forgot I ordered them, haha. They are super cool. Have one to my son and he loves it. They are pretty cheap, too, or used to be.
Great video, my only complaint is that you called the mechanism that "opens" the pen a 'button' - it's a lever. I don't think this same mechanism would work with a button, or at least it wouldn't be able to start from the bottom and work its way up in the satisfying way this pen does!
Pretty sure a button could be used to operate in the same way, but given how much force he had to use to crumple it, you probably want to have the mechanical advantage of the lever.
If I'm boiling water on the stove, and press force upon the pot, the boiling intensifies despite the same surface area and temperature. This might be worth exploring as a future video.
I seen these advertised not that long back, thought they looked too good to be true. If you leave it for too long it does get creases left behind when it's closed but they go after time.
Action lab In a super conductor Do the thing on top adds weird or it only measures the thing on the bottom Edit: Idk what im talking but did you get the point?
1:54 ish my kids and I felt this a week or so before last Christmas. My tire got caught off the curb and swung out car into the guardrail and my whole right front collapsed, car got totaled. We didn’t.
The tesla cybertruck has no crumple zones because it's unusual shape and design makes it more stiff. This is why the cybertruck is not street legal in Australia or the EU
I have two of the boxes from when you tried to make a science subscription box thing. I actually have one of the mechanisms still on my shelf. Too bad you couldn't do it long term.
Now if cars could uncrushes by themselves, that would be fantastic!
Make a car frame out of thousands of those pens.
Making a car un-crush itself is not too hard to imagine. Un-crushing the humans inside, that's altogether another matter.
Not a bad idea... Except only if the 'uncrushing' does not occur immediately and restore its shape in a split second. Otherwise a one or two vehicle accident can end up involving few hundred vehicles.
Insurance companies would be over the moon, or out of business
Great idea, however the components under the hood wouldn't be so uncrushed.
