Kamakaze Physics posted these pics of an aluminum can being being punctured by a ping pong ball at “near sonic speed”. -Link
There’s also some great video by the NIT Physics Lab from some of their other shooting experiments:

Ummmm… on the NIT video, are those *people* that are standing and walking downrange in the danger zone??? This is extremely irresponsible.
Wow, the can is denting before the ping pong ball even touches it. That’s quite a pressure wave.
There is a guy peeking his head out from behind a tree looking at the 700Khp tennis ball test shot.
Does he REALLY think he’s quick enough to get out of the way if that thing is deflected toward him?
My shirtsleeve math says that 700Kph is better than 600fps and he’s less than 100 feet away.
He won’t even have time to realize he’s about to get hit in the 1/6th of a second before that thing smashes into him.
Relax dudes. It’s just a ping pong ball. What damage could it do?
