Bottle Light is a novel energy-saving environmentally-friendly light, which makes full use of the potential of waste material by recycling so as to promote the awareness of people in environmental protection in the daily life. The work electricity of Bottle Light needs no external power supply. Only one empty bottle (such as a cola bottle and a mineral water bottle) is needed. Screw down the original bottle cap and screw on Bottle light. Then compress the air in the bottle repeatedly to make the piston of Bottle Light move up and down, which changes mechanical energy into electric energy and light LED.
