The London Science Museum added metal detecting technology to an R/C car so you can find treasure and have fun at the same time. The car beeps and lights up whenever it nears a metal object. It only costs $83, so I may actually end up getting one. Walking the beach with an old school metal detector is just far too boring for me. Sure I've found several expensive rings, but the women they're attached to usually start screaming before I can get them off.
