The purpose of this experiment was to see which liquid cleans coins the best. I became interested in this experiment because we get a lot of dirty coins when we get change. The information gained from this experiment will help others learn more about clean coins and how to make them look rich
There are a lot of websites that say salt and vinigar would be the best to clean coins. Some say gasoline, so I will be the best so I will see which one would be the best.
Coins are made of copper and nickel so the best way to clean is with the salt. The vinegar will give a boost in the cleaning process and the efficiency.
My hypothesis is salt and vinegar together will clean coins the best. I base my hypothesis on the research I have searched.
Get vinigar, salt, gasoline, coca-cola, 3 cups, 3 toothbrushes, flashlight, and coins.
Put gasoline in one cup
Put Salt and vinegar in another
Put coca-cola in another
Dip one coin in each cup
Keep the coin in the solution for 30 sec.
Brush them with toothbrush
Do this 3 times
Use a flashlight to see which coin has the strongest reflection.
10.Take picturesIV: Liquid
CV: Coin each time use the same liquid as the first time
The original purpose of this experiment was to see which liquid would be the best to clean a coin and make it shine the most. The results of the experiment was the Coka-Cola was the best to clean the coin. The next would be Salt and Vinegar was better than gasoline.
If you were ever to clean a coin you should use Coka-Cola.You should not use gasoline for two reasons. One it smells. Two it is not the best at cleaning coins.
