Italian YouTube science geek Giaco Whatever is completely obsessed with firing off Nerf darts in dramatic fashion. So much so that he invented what he calls a “lethal Nerf gun,” powered by 400 PSI of pressure, that can shoot a dart that pierces a Red Bull can.
In a follow-up experiment, he was able to get the Nerf dart’s speed up to Mach 2.3, or twice the speed of sound (that’s a little over 1,700 mph). Watch as the Nerf dart pierces a block of wood this time around.
