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:
2. Drill a hole in roofing to fit the circumference of the plastic bottle.
3. Push the bottle up through the hole in the roofing.
4. Seal the the bottle with polyester resin to prevent a leaking roof. [i]
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.
