I know it looks like something you’d use to bring Frankenstein to life, but it’s actually a scalp massager. A hedonic, drool-inducing scalp massager. You must try it. It’s rare as an adult to encounter a completely new sensory experience, but this thing will make your eyes roll back in your head. If you’ve ever seen live belly dancing, you know how it can make you feel vaguely uncomfortable, like it’s a little too sexual to be happening in a public place? The tingler is like that. Essentially, you move the thing up and down on someone’s head and watch their hair rise. The spines, for lack of a better word, are tipped with smooth bits of plastic that slip through your hair and slide around gently on your scalp. You’ve never seen goosebumps like these, people. There’s also a battery-powered option that vibrates, but things that vibrate make much more questionable gifts. Stick with the original, it will melt you.
