Make Your Own Air Battery
The video below shows three different electrolytes for a cell. Which electrolyte will be the best, producing the most voltage and current?
Making a waffle out of sodium acetate trihydrate. This is the same stuff that makes up “hot ice” and heating pads.
How is the liquid made?
Acid can release electricity from metal. What is an easy-to-find source of acid? Tomatoes!
The video above shows how an LED and a buzzer are powered by a tomato battery. It’s just two different metals dipped into mashed tomatoes. It even helps charge a AAA battery.
