Vibrating Soap

Vibrating Soap from I Want One Of Those

This absurd, but nevertheless essential, piece of bathroom paraphernalia, is a marvel of ingenuity. Quite simply it's a bar of soap that vibrates (quite vigorously!) when lifted from its soap dish. Buried deep inside the blueberry scented soap is a little motor that whirrs away, turning a seemingly innocent bar of soap into an indispensable bath toy. When you've finished with this 'auto-wash' (or whatever) soap, simply pop it back on its dish and it'll stop jigging about all over the place.

Well, I think this one explains itself.
