The Impossible Lamp is a work of craft and film by Jeeves Basu. It begins with a large wax candle sitting atop a clear plastic lampshade. Basu and his team had the difficult task of melting the wax so that it would drip over the mold, but cooling it before it could drip off. This time-lapse video shows how they did it.
