VACUUM GUN!!?? Supersonic Ping Pong Ball Video... pretty mental.

This is nuts... how to fire a ping ball at over mach speed... it obliterates a ping pong paddle/racket... wow!

EDIT: The Youtube video below is not the one from 'dump' which explains the physics.... I can't find that on youtube so here is the link... www.dump.com...



Not sure if this should be in 'science' or 'weapons'... feel free to move!

I am fascinated (and equally scared and horrified) by gun tech ... I know about electo-magnetic railguns... but I've never heard of a 'vacuum gun' and this sounds like the basis for one... crazy power potential...

I first saw this on dump.com which bills itself as 'family friendly'. ... but this seems very do-able and about a ten times scarier than a potato gun...

Do not try this at home he said.

Yeah!...

I actually watched the whole video..

I am now a NERD...LOL..

thanks..

Or Bruce Lee...


..(good fake!)

The best bit I loved????

Do not try this at home, we have years of experience and 20 degree's between us, do not try this at home!!!!!11!!11!

Then what happens??

In the high-speed the ball didn't quite go through the paddle..

Because???

They forgot to tighten the clamp!



Take away their degree's!

(Very cool though, I want one!) s&f

Best fake clip I've ever seen! So much awesome!

I'm so glad I got to see this video. I had no idea before this that having a collage degree was a prerequisite for doing things safely.

During the water filled test, the metal sheeting crumpled like it was nothing more than, as mentioned, tin foil. This is because the water added mass to the projectile, and also because of the way water delivers kinetic energy. I wonder what it would have been like, if the water was replaced with something a little thicker, like a jelly of some sort.

Bloody amazing video though, and a cool experiment!
