Without any source of light or electricity, families would be forced to work inside their houses in the dark. Whether it’s doing house chores or eating, they’ll be doing it in the dark.

A group of MIT students and Alfred Moser decided to do something amazing. With a little tweaking, the billions of empty plastic bottles that are being thrown away can be used to bring light to those who live without electricity.

Each empty bottle is filled with water and a bleach tablet dropped inside. The bottle is then installed through a hole that is made in the roof. During the day, the bleachy water refracts and spreads sunlight all over the house, thereby acting as a light bulb.

The use of solar light bulbs has also been very popular in India, Indonesia, and even Switzerland.
