HOW IT WORKS:
The metal strips and potato make a simple battery that create electricity to operate the clock.
- Each potato works as a device called a electricity chemical cell. It converts the chemical energy stored in the metal strips into electric energy.
- Two potatoes are needed to make electricity strong enough to run the clock.
- You can use other things other as battery resources, such as water, apples, oranges, tomatoes, etc.
- For further fun, put all the zinc plates and copper plates in one cup. WHAT WILL HAPPEN? Find it out by yourself.
- Cup Size: 5.5*5.5*6.8 cm
- Clock Size: 6.7*3.2* 1.2 cm
- Age Range: >=5 years old
- 1*Potato Clock Toy Set without Potato.
