Make a Battery
Want to shock your friends? Make a battery like the Italian physicist Alessandro Volta did 200 years ago.
What You Need
- Lemon Juice
- 9 1"x1" strips of paper towel
- 5 pennies or other copper coins
- 5 dimes or any other metal coin that is not copper
What To Do
- Soak the paper towel strips in the lemon juice.
- Make a pile of coins, alternating dimes and pennies separated by a lemon-soaked strip of paper towel.
- Moisten one finger tip on each hand and hold the pile between your fingers.
- You get a small shock or tingle
You have made a wet cell battery, the forerunner of the battery we buy at the hardware store. Lemon juice, and acid solution, conducts electricity created by the separated metals of the two coins.
