Since it is super cold out here today, it seemed like a good time to try out the IceCandle Project that I saw on the Make blog. The way this works is that you freeze water in a container with a void to hold the candle. I opted to create the void at the same time that the water freezes by placing a candle holder in the bottom of a bowl that holds the ice. Another modification that I made to this design was to use condoms instead of balloons to make the IceCandles.
There are photos of this project.
