The objective of this experiment is to generate an electric current by creating positive and negative ions and a conductor, In other words, we are trying to create electricity from simply just coins.

What is this experiment? It is a simple battery made from coins, we need to test the number of coins used and how it affects the amount of electricity produced.

How to build this experiment:

1. Put vinegar and salt together.
2. Cut paper towels into small squares; put them into the solution of salt and vinegar.
3. Put paper towel between every penny and every nickel
4. The more you add coins the higher the voltage.

Vinegar à Electrolyte

Vinegar breaks salt into positive and negative ions.

Salt à NaCl (ions)

NaCl à Na+   + Cl

The zinc has positive charge

Penny has negative charge

Table of results:

In conclusion as we can see, as we increase the number of coins, the voltage increases. Therefore we can see a positive relationship between them.
