This is a video of Youtuber Giaco Whatever building a metal air-cannon strong enough to shoot a NERF dart through a Red Bull can at an incredible distance of like five inches. The pressure behind the dart at launch is around 400PSI, or about the pressure experienced at 870-feet underwater. For reference, my car tires are inflated to 0PSI, because somebody just slashed them. And if I find out who did it we are going to HAVE SOME WORDS. And those words will probably begin and end with, 'Hey -- you! Dammit, of course you have a knife.'
Keep going for the video but skip to the very end if you just wanna see the shot, the rest is him constructing the cannon. Also, get a slow-motion camera, man.
Thanks to Mark V, who's going to build a NERF dart cannon that can shoot them through a castle wall.
