See how to make a penny battery today and always have a quick source of power in an emergency. Perfect for small projects like powering a small clock or LED’s light bulbs.
I will start off by saying… obviously, this is not going to be powering anything significant, but I want to share this with you because believe it or not, 10 pennies can light up an LED for over 2 days solid. This could come in very handy if you need a light in the dark. This old school, the fun project could be a great science fair project for kids of any age.
This 10 penny battery can produce around 6 volts. That’s enough to power up to 2 LED’s. Let your imagination run wild and make a few. Check out how to make one 🙂
