The rainmaker: In every home I see at least one of these. Everyone in the home uses it but never at the same time. its a room within a room. A very small room. Sometimes with clear glass on one of the sides. A door or drape is the portal to enter. Once inside there are a series of knobs. After turning them, I hear a noise as if I am about to take off on an airplane; and within a second, rain covers me and I am soaked head to toe.
