Here's another clip from the UK telly show Sex: How to Do Everything
. This one is rather shocking, so to speak. The curious couple tries out a Violet Wand
, which is a device that puts out low current, high voltage, high-frequency electricity via a Tesla coil, emitting sparks of various colors (most commonly purple, red, blue or pink) that can be used to stimulate the skin. It was "originally sold as a supposed medical device claimed to be useful in electrotherapy, though, since the 1990s, it has been used by some into BDSM sex as a sexual stimulation device."
