Juice Battery

Project Number: 63

Description: Replace the soda in the liquid energy source with fruit juice. Sour tasting juices like lemon or grapefruit work best. Measure the voltage and the current for your juice battery like you did with the soda. Try different juices and compare them. Don't drink any juice in this project. Wash the electrodes and the liquid holder.

Snappy: Some fruits and vegetables have a sour taste because they are lightly acidic. This acid can be used to produce electricity just like the cola and the battery does. Using the natural chemical energy in fruit is a very green (environmentally friendly) way to produce electricity.
