Wet Lamp.... extend extend

"The WET Lamp is an elegant and playful series of glass lamps with an alluring water-submerged light bulb at its center. Putting an exposed light bulb in water certainly raises some eyebrows, but it also creates an intriguingly simple dimmer switch. When a thin silver rod is slid into the water, the WET Lamp turns on and becomes progressively brighter as the rod is submerged.
Despite its precarious concept, the Wet lamp is a completely safe and isolated system of low voltage power."
