Making Light Without Electricity

This seems pretty cool. A man in Brazil figured out how to make light without electricity - and the cost is pennies.

All he did was use plastic bottles filled with water and a bit of bleach. Basically you fill a 2 Litre empty bottle with water and 2 capfuls of bleach to prevent algae. Drill a small hole in your roof, pop the bottle through, caulk the opening, stick something black over the cap (which is outside) and you're good to go. He uses black film canisters - which might be hard to get so I''m going to start collecting them now.
