How to make cement batteries?

·       Material Required?

Aluminum cans (two pieces)

·        A copper wire coiled

·        Plastic cap in the bottom

·        A saltwater solution

·        Volt meter

We’re going to use a mixture of two percent concrete and other things are crystals.

We will take some amount of white cement and then add some amount of salt water solution to it. Meanwhile, Mix the solution and cement

When mixing is over, put coil copper inside the can.

Make sure Copper and aluminum never contact with each other. Therefore, we use a plastic cap at the bottom of the copper coil.

Before and after drying measure if there is any voltage or

Copper is positively charged and aluminum is minus.

Test the batteries, the voltage, and the amperage after drying of batteries.
