Liter of Light is a Non-Profit Organisation with the aim to provide a long term source of light to the underprivileged that do not have access to electricity or just cannot afford it. The idea we follow is pretty simple we use a 1.25 Ltr. Cola Bottle with purified water and bleach installing it onto the roof of a sheet house. The water inside the bottle refracts the sunlight during the daytime and provides as much light as a 55 watt light bulb. As this form of light requires the sun's energy it works only during the day.
