Time for yet another Mathmos lamp! Continuing their candlelight theme, Float, instructs you to fill its glass with water, insert a candle into the glass, and then light it. Instead of the candle burning down the way, the light remains where it is, and the body of the candle moves upward due to its desire to float on the surface of the water.

Fill the mouth blown glass vessel with water to the level of the chrome candle guide. Float one of the unique Mathmos Candles in the water and light. The flame will stay in the same place as the candle reduces in size casting moving light through water, glass and metal. (Works with most household candles.)
