Ever dreamed of being able to wash your hands with a laser beam instead of water? Yeah, me too. You can get pretty close with this LED facet gadget. It screws onto the end of your facet and passes the stream of water through a light chamber contain LEDs. It will even turn the color red when water hits 89 degrees. Best part is it runs on batteries, which is a hell of a lot safer than the one I made that plugged into the wall.
