Every played with moldable plastic?  No, burning plastic spoons with a lighter doesn't count.

Sugru is a pretty neat material that you can mold and play around with like play-doh, but will eventually harden into a waterproof rubber. There's tons of stuff you can do with it, but I've always been impressed with the ideas that the company itself comes up with.

Along comes a Sugru water gatling gun. To be fair, YES you can make this thing with Sugru, but it would appear that you most likely also need about $250 parts from a hardware store, an aluminum c&c machine and a degree in mechanical engineering.

HOWEVER....I'd gladly buy one.
