The Tingler looks like it could help you whip up a batch of scrambled eggs, but it is described as the "Ultimate Head Massager." According to their website, it's made from copper, "which acts as a conductor tapping into your electrical fields." I'm not sure if I want anyone doing that--hey man, step away from my electrical fields! Seriously, though, I remember trying this once, and it is indeed a spine-tingling experience. (It's no Brookstone Body-Massage Chair, however).
