This metal is too bouncy

A little while ago I made something called an atomic trampoline, and I think it's pretty cool. This is because when you drop something on it like a ball bearing, it just keeps on bouncing like it's never going to stop.

What I've been really wanting to do though is take two of the trampolines that I've made, and see if anything weird happens, if I try bouncing a ball bearing between them.

When it says "Ignore air resistance, friction, and energy loss"

The the sound, the bounciness... I think... I think this unlocked some neural pathway in my brain. That felt so good...

I'm sure it's not lost on you that this is what happens to the particles in a gas when you compress it.

With the thumbnail, i intially thought it was gonna be some kind of hydraulic press test.

i was fully expecting him to drop one atomic trampoline on the other

[weabrew]

Now glue an ant on it, train him for space

"Bounced a lot", "bounced a ridiculous amount"... Truly the most scientific dialogue I've heard..

[tripdrakony]

get in contact with the slowmoguys, this has to be one hell of a interesting highspeed footage

This is something you need to get the Slowmo Guys on. There is obvious deflection occurring in the metal, but you need a very high speed camera to detect it.

This shows that almost all the ball's kinetic energy losses are from air viscosity.
It has orders of magnitude more collisions before stopping when it's bounced a shorter distance between two plates as opposed to freely.
Please try bouncing it in vacuum. You can put the trampoline in a clear sealed tube and drop it with a magnet. Maybe even try it with helium which has very low viscosity

This is the true version of analog audio oscillation. I've only ever heard the digital wave form while switching frequency on my ham. This is amazing!!

Atomic trampoline sounds like something Reed Richards would make

[Patrick-zrtv]

My voice right at the end of delivering a clear and logical argument that would otherwise have convinced the opposition of my point:

[malcontender]

The math involved in that last two seconds of bouncing is utterly frightening. It's doing thousands of rebounds.

[SoulBoyDoesArt]

NileRed doing asmr is something else 😂

I analysed the audio of the ball bouncing and found out that the frequency of the audio just at the end of the bounce is around 12kHz, which means that it was bouncing almost 12000 times a second!

Edit: Some people have interesting theories and suggestions, since this turned our to be a good debate, i just want to clear out some info:

1- the mic i used was a regular mobile phone mic nothing special, such mics can detect up to 16kHz if I'm not wrong.

2- 12kHz means there are 12000 individual beats in a second, which means the ball was hitting each surface 6000 times a second.

3- I tried to simplify this to be just for fun, i know i am probably wrong to some extent, if we want this to be a research it would need much more advanced equipment than i have and more specialised people than me.

4- Maybe if TheSlowMoGuys could capture some closeup very high speed footage we would be able to count the number of bounces more accurately, it would also be more fun.

It’s a nice example of what confinement does when combined with the conservation of momentum. As you remove the effects of gravity by shortening the distance between the elastic surfaces the momentum of the ball is converted to rapid reversals of velocity. The kinetic energy is conserved, but the acceleration and deceleration caused by gravity approaches zero as the amount of time allotted to it approaches zero.

So the sound effects on the 3 blue 1 brown collision video were surprisingly accurate!
