Taking advantage of discarded plastic bottles, we can completely make plastic light bulbs emitting light equivalent to 55 W. electric light bulbs.

Each empty plastic bottle is filled with water and put in an extra bleach. After that, the plastic bottle is placed in a round hole carved on the metal roofing roof. During the day, bleach in plastic bottles refracts light from the Sun and disperses light around the house like a light bulb.

With a simple and effective fabrication method, anyone can make a water bottle light without electricity for their home to reduce their monthly electricity bill.
