brazilian lights

our brazilian friend renato sent us this interesting eco-tip...
Here is a video about a clever and ingenuous invention. Light bulbs made out of plastic bottles. They are filled with water and a little bit of bleach (to keep germs away), then the caps are protected with photographic film (to protect them from being dried out by the sun rays), and bingo. Each bottle produces as much light as a 50W bulb. How come we never thought of that before???
