Guess What? 16

In 1958, John Houghtaling invented Magic Fingers, a device mounted onto a hotel bed that would shake the mattress under you for 15 minutes, promising escape from the work-a-day non-vibrating bed world.  Let me describe the experience to you.  First you drop 25 cents into the coin box at the head of the bed.  There is a buzz from deep within the mattress, and very quickly the fine lines printed on the bedspread go into soft focus.  Panicked, you wonder whether it’s scientifically possible to rattle the eyes out of your head.  Eventually you are able to let go and enjoy the body massage by imagining that you are sleeping on a giant purring cat.
