This is my first time watching any videos from this channel but I've got to say this is the quality content that we need more of on UA-cam. More scientific than a lot of "scientific" channels really are and you can tell this man is just enjoying himself while he figures out how to catch an egg. Every man wishes he could express his inner child by catching really fast eggs.
I appreciate the time you take to set up and film these experiments! And you do such a wonderful job putting YOURSELF into it. Quite literally😂 your joy when you succeed is like a child and it’s refreshing! As Destin from Smarter Every Day said, you and him have similar minds, and I have to say I’m of a similar mind as well!

10:44 Dang. That egg is coming out of the barrel with magnum handgun energy. It's so interesting to see the physical behavior of what is basically a CaCO3 jacketed, viscous liquid core, shotgun slug.
Potato guns can do some serious work if they are designed right, I've got one that shoots golfballs at 750 FPS and makes about 875 ft-lbs of muzzle energy, and that's just with propane and atmospheric air. Another one I made was capable of magnum rifle energy levels, a stoichiometric mix of air and fuel were compressed (to 10 bars) into it's chamber which was contained by a burst disc between the chamber and barrel, then once the chamber was pressurized an electric spark ignites the mixture and the pressure (about 500 PSI) generated breaks the burst disc, made of either stacked layers of aluminum foil or cut out pieces of 2-liter soda bottle walls. That gun could fire golfballs at 2100 FPS, making just shy of 7,000 ft-lbs of energy😁. Recoil wasn't too bad considering the gun weighed 40 pounds, though it was still pretty stout and definitely shoved me around pretty good lol.
*@Bruce Yeany* 7:50 I assume you could use some more papers at the back portions of the rings? (or multiple spaced layers of that cloth sheet?) I assume that because the egg has lost some speed, it doesn't impact the paper as hard then, so then you can increase the layers, to keep the "impact energy" constant, near the maximum that the shell can withstand. You can also experiment by using silk-paper (the thinnest you can find), to add "fractions" of a newspaper's worth of hardness, to really fine-tune the impact-energy.
What a wonderful no nonsense, densely interesting video! I LOVE this pacing. Other creators would have made a video for each test you've made, but you chose to not waste any time and keep all the interesting parts in a nice condensed package: I absolutely commend your effort.

I want to see a Bruce Yeany and Tech Ingredients collaboration. I know your content is gear towards your students Bruce but you're the right person for this sort of thing. Making education fun and approachable for anyone who cares to seek it.
Great demonstration of the nonlinear relationship between speed and kinetic energy (which I always try to bear this in mind when driving or cycling). Before you got to the newspaper setup, I wondered about using a series of loosely-held silk cloths - strong but light and flexible - starting out small at the front. I think that would give longer contact times than tearing paper. Perhaps aerodynamic benefits too. Really enthralling video, thank you!
Thank you for sharing your experiments with us. I enjoy this so much! I liked you didn't gave up on catching the vertically flying egg, after (at least) 3 times.
Splendid experiment(s), but God knows how long it took you! 10/10 for persistence. I'm glad you found two solutions. It's interesting how gradual the deceleration has to be to avoid breakage,
Another great video. You remind me of my physics teacher many years ago who brought experiments to life. Eggs from younger chickens generally have thicker shells. They are also a bit smaller
Let's all say: EGGSELLANT! Eggs Sell like ants... We eat too many! Shoot them at stuff to see when and how you can't break them. Very cool video! Thanks for your efforts and documenting the adventure. Peace and Love.
You could try taping a bamboo skewer about 7x the length of the egg to the egg, like the stick on a bottle rocket, to see if that keeps the egg from turning sideways. Or affixing tailfins or perhaps the tail of a badminton shuttlecock.
It's surprising the egg didn't break inside the cannon. It must have something to do with that capsule that can be seen trailing the egg. 1:53 Was a favourite moment of mine.
the fitting around the egg is called a sabot, I experimented with several designs and they are shown in the first video of this series. ua-cam.com/video/33dnlFwjngk/v-deo.html
As well as the fact that the egg is experiencing the acceleration along the strongest axis - IE: Top to bottom, not side on like it orients itself to after the shot.
@@diox8tony yeah lol, just fire it in reverse. The laws of physics work in reverse, so surely that'll work. Actually, let's break the eggs in reverse too while we're at it.
*@Bruce Yeany* 6:45 Use 2 water bubble levels on the barrel (measuring: right/left & back/forth) to know when you point the barrel straight up. (then account for wind, if needed) 9:44 Ah, finally! :D
Always great to see your fun experiments! You're students were lucky to have you. My science teachers were mostly excellent, I guess I was lucky too ;-) (Mostly, because my chemistry teacher in high school didn't really know much chemistry. She was perfectly nice and made an effort, but her lack of knowledge was a bit of a problem.)
Holey sheet, that was some eggcellent tests. It cracked me up when you cracked that egg you were trying to save. Then, to see you trip, I would have lost it if that egg hit you right after. It was nice to see you finally catch it, though.
Oh.... In the beginning of this video I had an idea to make a comment to use 8 sheet of paper to slow it down, 8 is like the magical number for paper, like you can only fold a paper 8 times; but then I saw that you had an even better idea on the same concept at around 7:44. Sorry for poor spelling and grammar, English is my 3rd language after Swedish and Finnish.
@@YeanyScience I wait on baited breath! Seems to me rifling might have some slight reduction in muzzle velocity vs the smoothbore at the trade-off of accuracy. I'm also extremely curious how the rifling would affect the sabot if at all. Also also I feel that might fix the issue with the egg always rotating perpendicular to the airflow and if it does that could both greatly increase accuracy but also presumably increase range even with a lower muzzle velocity at the same pressure.
Loved the effort here. So awesome not giving up and trying a new idea. If you want it to go ridiculously fast you could vacuum the air out of the barrel
Very interesting! Try hanging sheets of silk vertically only from the top and let the bottom hand loose as you did with the news paper. The egg will not break and the silk will not tear. Also, to increase the muzzle velocity of your air cannon, tape off the muzzle with thin packing tape, pull a vacuum on the barrel and fire while the inside of the barrel is under vacuum. You will get a supersonic or close to supersonic projectile. The acceleration may break the egg however.
With the sheet method being so successful with slightly slower eggs, and the egg successfully passing through the sheet without breaking, to me the most obvious solution would just have been to add multiple sheets spaced apart. My guess for that 300mph egg, it would have required only three sheets, but maybe it would also stop in two.
I tested several materials, the problem with using the sheets and other materials to slow the eggs down is that about half the time they will break passing through them. I tried four sheets but didn't show it, the egg broke on the second one
Eggselent demonstration! It's absolutely smashing! OK, no more bad yokes... Is the footage you recorded detailed enough for taking v/dv measurements? That'd be a goldmine of data for the students that are interested in going further. :)
funny I was just thinking along the same lines, I thought these would make some interesting problems, I've been thinking of getting some photogates to get some more accurate readings
I am a bit surprised by 8:45 (the egg hitting through papers). It looks like the egg's velocity is not changing much. But then the kinetic energy is proportion to velocity squared, which probably saves the egg.
it would be interesting to know how much the speed decreased. I fired the eggs into the sheets at lower speeds and found that the sheet could safely stop it around 150 mph
I think the main problem for a lot of the failed attempts is just a matter of weight and momentum of the sheet. With the lighter sheets the egg will just punch through, but the reinforced sheets become so heavy that to the egg at 300mph they might as well be a solid wall. Basically, even if the sheet has lots of give, the egg will already shatter from trying to overcome the static momentum uf the sheet before it manages to impart enough kinetic energy for the sheet to start moving with the egg. Thats also why it doesn't matter whether the sheet is attached directly to ropes, or to a parachute. It's overcoming the momentum of the sheet itself that's the problem. So ideally whatever material you use to catch the egg should be as light, elastic, and high-tensile strength as possible.
was out in the open, nothing and nobody anywhere near when out of nowhere I was hit by an egg! can you imagine my surprise? now I know the culprit. It was you and your weaponsgrade egglauncher! 😉😄🤣 good work mate, keep em coming!
hey Bruce, let's test your sabot precision. you should be able to catch the egg by shooting it down another barrel of equal length with a cap on the end. this method uses the seal formed by the sabot to create a cushion when entering the second barrel. you could guarantee the entrance into the second barrel by using a coupler with holes drilled in it for exhaust.
xD great experiments! I thought you weren't going to get it Bruce, too much speed! Was starting to think about some sort of fabric made out of spider webs... xD
the previous video shows a lot better just how dangerous a 300 mph egg can be, ua-cam.com/video/oczS6uEtTow/v-deo.html can't wait to see results of 450 mph eggs
You can prevent the egg from flying sideways as it exits the tube by adding a short cylindrical net at the exit. This will stabilize the egg after the pressure drop and will not let it spin. When shooting the egg vertically with zero wind velocity, try to let the egg fall back into the cannon. I'm curious to know if it's feasible.
This was very cool. Could you glue card stock fins on the eggs to make them fly long-ways? You could then check to see if orientation changes anything.
I would love to see a redirection of the egg along a curved path, and whether the friction would be enough to slow it down or if the centripetal(or frictional) forces would be too much. The other being into a well timed cannon of air. That would be amazing to watch; a 200mph egg brought to a standstill by a strong headwind.
@@YeanyScience damn. Great minds haha. Thanks for the response! I'll take that as tacit confirmation that you'll fire an empty air cannon at a flying egg ;) maybe a free falling egg, could be fun. Momentary hovering egg.
I liked the idea of a hanging pillow. If you had used a smaller one, perhaps the egg would have survived. The slow motion video shows the pillow slowly moving back under the impact of the egg breaking. A smaller and lighter cushion would have less inertia, so the backward movement would be faster and the egg would experience less overload. it's just a theory
Okay, I''m at 2:50 seconds and I've got an idea as to how to stop the egg, I'm going comment this now and see if you came up with it, I think a way to stop the egg that would almost certainly eventually work is having many layers of sheets separated with air gaps, The egg should loose energy tearing through the first few sheets and eventually would stop, I think this idea should be semi infinitely saleable, up until the point when launching the egg becomes to violent, or air resistance becomes so great that the egg cannot withstand those forces. Although you'd need a LOT of sheets to stop an egg going so fast that those are a worry Edit one: oh look, Simple air resistance and distance was enough Edit two: YEAH LOOK AT THAT ! Ya totally thought of it, That box/insulation idea was also great
I wonder if you could come up with a structure - something like a panel with ribbons across it, half an egg wide, then a half egg gap, repeat - and get the egg to catch the ribbon and start rotating. Then put stopping material nearby behind it, at an appropriate distance that the egg rotates to the strong orientation, and impacts before air resistance turns it back?
@@YeanyScience yes a project ,when I was on Mark Rober’s course learning a bit more about how to plan and carry out projects. Great fun always more to learn and more questions.
I really enjoyed this. How about glueing dart flights to the small end of the egg to give it some aerodynamic stability? I was surprised that eggs like to fly sideways, I wouldn't have expected this. The only possible next step is supersonic egg. "How do you like your eggs in the morning? I like mine with a boom!"
This was awesome, a little mental math on why some of the other things failed e.g. pillow, is you're effectively hitting an egg with a pillow traveling 300mph so that will not work. But most importantly Newton's 3rd law, need to have things light enough that can not create large forces, hence why the newspaper worked so well while a large force may have been able to be done by the egg the egg absolutely could not enact a large force on something like newspaper because the newspaper can't do the same force to it
Nice. Have you thought about trying to get them supersonic by evacuating the barrel before firing? I'm not sure how an egg would deal with hitting a wall of air at supersonic speeds, but it might be interesting to try.
i love that the first success was immediately followed by you dropping it. was just the right amount humorous in my opinion.
that was my third try, with all the papers, the first one had the egg break in the cannon barrel, second one hid the wood frame, third one worked

you could guarantee the entrance into the second barrel by using a coupler with holes drilled in it for exhaust.
The bike helmet and wood panel station wagon really captures this channel's vibe. lol
xD great experiments! I thought you weren't going to get it Bruce, too much speed!
Was starting to think about some sort of fabric made out of spider webs... xD
As hard as it was for 300 mph, I can't imagine trying this for 430 mph,
I'm now imagining the sheer confusion of a hiker getting blasted with a terminal velocity egg from above out of nowhere
You did it three different ways!💯
Not only has this video educated me on physics, but it has also implanted a fear of 300 MPH eggs in me.
the previous video shows a lot better just how dangerous a 300 mph egg can be,

can't wait to see results of 450 mph eggs
Bruce, thanks for the vid, it was entertaining and informative.
You can prevent the egg from flying sideways as it exits the tube by adding a short cylindrical net at the exit. This will stabilize the egg after the pressure drop and will not let it spin. When shooting the egg vertically with zero wind velocity, try to let the egg fall back into the cannon. I'm curious to know if it's feasible.
Well held, sir! Might I suggest putting a rain cover on your cycling helmet?
Very interesting and fun video, cheers Bruce.
actually a fairly interesting watch. I wonder if the results would differ if a bore was introduced to the barrel
This was very cool. Could you glue card stock fins on the eggs to make them fly long-ways? You could then check to see if orientation changes anything.
I would love to see a redirection of the egg along a curved path, and whether the friction would be enough to slow it down or if the centripetal(or frictional) forces would be too much.
The other being into a well timed cannon of air. That would be amazing to watch; a 200mph egg brought to a standstill by a strong headwind.
there were some tests that didn't get shown, one was trying a slight redirection, tried it a few different ways, all of them broke the egg
@@YeanyScience damn. Great minds haha. Thanks for the response!
I'll take that as tacit confirmation that you'll fire an empty air cannon at a flying egg ;) maybe a free falling egg, could be fun. Momentary hovering egg.
4:09 The dog like hope he dont catch me with this. Oh man, he didnt even notice me, yayuh!
I liked the idea of a hanging pillow. If you had used a smaller one, perhaps the egg would have survived. The slow motion video shows the pillow slowly moving back under the impact of the egg breaking. A smaller and lighter cushion would have less inertia, so the backward movement would be faster and the egg would experience less overload. it's just a theory
This is how UA-cam used to be. I miss this stuff.
Okay, I''m at 2:50 seconds and I've got an idea as to how to stop the egg, I'm going comment this now and see if you came up with it, I think a way to stop the egg that would almost certainly eventually work is having many layers of sheets separated with air gaps, The egg should loose energy tearing through the first few sheets and eventually would stop, I think this idea should be semi infinitely saleable, up until the point when launching the egg becomes to violent, or air resistance becomes so great that the egg cannot withstand those forces. Although you'd need a LOT of sheets to stop an egg going so fast that those are a worry
Edit one: oh look, Simple air resistance and distance was enough
Edit two: YEAH LOOK AT THAT ! Ya totally thought of it, That box/insulation idea was also great
09:58 _Teacher down! Teacher down! Repeat, teacher down! Teacher down!_
LOL, my wife made me include that
@@YeanyScience ehy... Behind a great man there is always a great woman! Kudos to both of you! Inspiring 👏🏻
I love your channel!
Thank you Bruce. Master class as always
It would be a fun engineering competition to see who could stop the egg in the shortest distance without breaking it!
Dude, you are cracked. ;P
Love the persistence!
Super fun ideas!! - just needs some better production and presentation, and you'll rocket to the top of yt in no time
seeing a middle-aged man shooting up an egg and trying to catch it with a weird bedsheet net contraption somehow released some serotonin xD
I wonder if you could come up with a structure - something like a panel with ribbons across it, half an egg wide, then a half egg gap, repeat - and get the egg to catch the ribbon and start rotating. Then put stopping material nearby behind it, at an appropriate distance that the egg rotates to the strong orientation, and impacts before air resistance turns it back?
It’s always nice to see someone who is as mad as me!
Brilliant video thanks
Ah, I see that you have a passion for breaking eggs also.
@@YeanyScience yes a project ,when I was on Mark Rober’s course learning a bit more about how to plan and carry out projects. Great fun always more to learn and more questions.
I really enjoyed this. How about glueing dart flights to the small end of the egg to give it some aerodynamic stability? I was surprised that eggs like to fly sideways, I wouldn't have expected this.
The only possible next step is supersonic egg. "How do you like your eggs in the morning? I like mine with a boom!"
I'm expecting supersonic eggs soon. Shockwave and all. Make a new entry for Guinness!
This was awesome, a little mental math on why some of the other things failed e.g. pillow, is you're effectively hitting an egg with a pillow traveling 300mph so that will not work. But most importantly Newton's 3rd law, need to have things light enough that can not create large forces, hence why the newspaper worked so well while a large force may have been able to be done by the egg the egg absolutely could not enact a large force on something like newspaper because the newspaper can't do the same force to it
Nice. Have you thought about trying to get them supersonic by evacuating the barrel before firing? I'm not sure how an egg would deal with hitting a wall of air at supersonic speeds, but it might be interesting to try.
What a joy to watch! Thank you!
Dude really thought he could make the cannon perfectly plumb by eye. Somebody a half mile away got smoked by an egg mortar
