High Speed Camera Shots

I managed to borrow a high speed camera from work and with a person who does physics demonstrations at Cal Poly Pomona I got high speed footage of a ping pong ball shooting through some cans:



The ping pong ball is being launched entirely by air rushing into the pipe to fill a vacuum. You can see that a shockwave comes ahead of the ping pong ball denting the can before the ball even reaches it.

Here is a basic description of the experiment.

Here is a normal speed video which I was not involved with:


Also somewhat impressive is their full list of Physics Demonstrations.
