McGyvering a battery using coins

May 19, 2016

A battery can be made using coins, salt and vinegar.  All you need is some paper towel!

We made a solution out of salt and vinegar and dipped small circles of paper towel in it.  

We stacked a penny, soaked towel, dime, soaked towel etc.  Coins can’t touch, and papers can’t touch.

When the stack gets tall enough, there is enough potential difference to light up a clock face.

We used the multimeter to check the voltage across the battery.

It’s pretty neat to see how we can make a battery using household materials.
