In these shots, a ping-pong ball fired at an unnamed “near-sonic” speed destroys a metal can that, you’ll note, is first dented just by the cushion of air coming from the barrel. Kinda makes you wonder how much devastation the cannon could have gotten done without any projectile at all. If this rings of deja-vu, it’s because yesterday I posted a video series of a tennis-ball cannon that I mistakenly thought was the same device. Consider it a two-fer and enjoy the bonus annihilation.
