Thought this was pretty neat. Decided to build one. For $20, it can't be beat. The local dollar store has 16 tea cup candles for $1. Should cut heating cost significantly and cost just pennies a day. Thought I'd share.
2 Bricks cut in half, on top of a ceramic base with 2 ceramic flower vases (one inside the other) held together with a 1/2 bolt, washer and nuts. 3-4 tea cup candles.
