Do-it-yourself neon. This thin electro-luminescent wire (el-wire) glows very brightly. You can bend it easily, tie it to anything. It produces essentially no heat. Best all of it runs on batteries, meaning you can wear it or use it on your bicycle. We make signs with it and, of course, some wild costumes. El-wire (also called Live Wire) has been used to great effect in the night parades at Burning Man; I still have vivid memories of an animated neon kangaroo (mounted on the side of a bike) galloping across the desert. It comes in various lengths from .5 m to 10 m (you can cut it if you know what you are doing) and in eight colors. You can also make it strobe. It is the world’s most flexible light. It is very cool stuff.
