How to make a light source out of plastic bottles.
Well over a billion people on our planet don't have access to electricity and this D.I.Y. solar light can brighten homes during the day and replace toxic kerosine lamps.

4 easy steps to light a room with a solar bottle lamp:
- Add a couple teaspoons of bleach to keep the water clean.
- Drill a hole in roofing to fit the circumference of the plastic bottle.
- Push the bottle up through the hole in the roofing.
- Seal the the bottle with polyester resin to prevent a leaking roof.
It's a stunningly simple lighting solution: sunlight passes through the water inside the bottle, refracting light, and brightening the room.
Even though you might not insert a 2-liter bottle into your roof, this might also come in handy if you're want to illuminate the inside of a tree-house.
