Enviro Battery - Green Science Kit for Children

This is a cool product for getting children interested in science and more specifically power. It teaches children how to generate electricity using lemons, potatoes and plants, it also teaches them how to make batteries from scratch. They can then use those to power clocks, lights and buzzers and even make games from them.
Be amazed at how the potato, salt water and mud light up a bulb or a sound buzzer. Includes experiment guide for making a coin battery, a fork battery, a potato buzz wire game, and more.
