Have your children outgrown their old Nerf guns but you can’t bring yourself to get rid of them? Give those abandoned toys new life through some clever DIY modifications. In his latest video, YouTuber Giaco Whatever demonstrates how liquid nitrogen can be used to engineer a more powerful Nerf gun.
According to Eric Limer for Popular Mechanics: "Equal parts impressive and impractical, this blaster fires by trapping expanding liquid nitrogen in a chamber where its only way out is a DIY burst disk made of potato chip bag. The result is that the blaster doesn't fire when the trigger is pulled, but rather at the point of burst-disk failure a small but indeterminable amount of time later. That, plus an arduous reloading process that involves replacing the disk and pouring some bubbling liquid nitrogen through a funnel makes this blaster extremely impractical (not that you'd ever want to point it at a person), but also a hell of a lot of fun to watch."
