It starts off with your typical slow-motion video of just a normal airbag inflating and busting through the steering-wheel plastic. But after that, the videographer disassembles an airbag down to the explosive core to show how that works. The result is just a split-second burst of sound and gas, but in slow motion, you get a pretty spectacular show of ultra-hot gas and even some sparks radiating from all the little holes around the cartridge.
The video wraps up with a makeshift cannon with the cartridge at the bottom and a cylindrical wooden projectile to get an idea of the force generated by the airbag. The results are remarkable, with the projectile ripping a clean hole in the cover facing the cannon and smashing into a heavy tool case. And that's as good a time as any to remind readers to not try this at home, just enjoy the video.
