When I was 7 my older sister and all of the lifeguards at my neighborhood pool convinced me that there was a thing called a wetifyer. If you turned the wetifyer off then once you got out of the pool you would no longer be wet. I believed them until I finally became a lifeguard myself and asked my boss where the wetifyer was located...
