This is one of those things that you’re mom don’t want you to play with. Water- filled Ping Pong balls – match it with Pneumatic Cannon,  now that really is scary.

At some point, it is cool. The idea of shooting a plywood with a ping pong ball and actually putting a whole on it is quite awesome. But I think that it’s not the pneumatic cannon that is being impressive. But the effect of water-filled ping pong balls. Try freezing it ang firing it using this cannon, it will be just like using rock as a bullet. It would really really hurt or much worse. Seems like ping pong balls is not that safe anymore.

In watching this video, I say, parental guidance is recommended.
