The cinder block "heater" - a cinder block that has a stepping stone on the top as a cover. Inside one cavity of the cinder block I added a light bulb. The light bulb puts off just enough heat to keep the concrete block warm. The waterer then sits on top of the concrete and keeps it just warm enough not to freeze. GREAT Idea!
