Fruit batteries

Fruit batteries by jerry loomer a battery is an electronic device that changes chemical energy into electrical energy. the chemical energy is sort of like the energy in the food we eat. when we want to run or jump, our bodies change the food (chemical energy) into motion (kinetic energy). similarly, the chemicals in a battery are storing energy...
