Description

A Two Potato Clock is a fun and educational science project that demonstrates how chemical energy in a potato can be converted into electrical energy to power a small device, such as a digital clock.

Make your fruits and vegetables work for you. By inserting the zinc and copper strips into the potatoes, you will create an oxidation/reduction reaction that is converted to low voltage. Enough power is created to operate the simple LED clock on the base.

• This helps to keep any desired distance between the min. and max. span easily.
• Fruit or potato does not include.
