All you need is a dean plastic bottle. Fill it with water from the tap and close it with a black top. The black top attracts the sun. A drop of bleach, the kind you use to clean the house, is added to the water to keep it clean. Then a small hole is cut in the roof of the room where you want the light, and the bottles pushed through the hole. While there's sunlight outside, the light will be carried through the water into the room below. And it's much stronger than the light from a candle!
