PLASTIC SODA BOTTLE BECOMES A LIGHT SOURCE
Free Light Source Anyone?
A new, inexpensive, energy-efficient light source: the two-liter soda bottle. No electricity required. When sunlight hits the roof and top of the bottle, light is refracted within the water and produces light within the space. The output of this thrifty fixture is equivalent to that of a 50 watt incandescent lamp. Here's the recipe:
2-liter soda bottle
A little less than 2-liters of clean water
1 Film canister
Fill the soda bottle with clean water and bleach. Place the film canister over the cap. Insert soda bottle into a hole in the roof.
VOILĄ, an inexpensive, no-energy light fixture!
