This is a home made Galvanic Skin Response sensor (a.k.a. lie detector). It's just a Lego motor wire and aluminium foil hooked up together to your fingers, giving an electrical reading to fingers, by measuring how relaxed and dry your fingers are. If you have Lego parts laying around, you could consider building your own.
