Plastic bottles are a frustration for most environmentalists. Their quantity grows and very few get recycled. Here is another idea for plastic bottles upcycling - a free light bulb that doesn't add to an electricity bill and doesn't pollute. A simple solution to a large problem especially in third world countries. If you would like to make such a lamp, you will need:
- a plastic bottle
- chlorine
- water
- sun
