Science is fun! You don't believe it? Let's try this stuff;

The Taco Sauce Cleaner:

• You might have heard that taco sauce is great at cleaning pennies. Try this experiment to find out of if it's true, and what ingredients might do the trick.

You'll need:

• Dirty pennies (try to collect tarnished pennies that all look the same)
• Taco sauce  (mild sauce from Taco Bell works well)
• Vinegar
• Tomato paste
• Salt
• Water
• Small plates
• Masking tape or sticky note

Instructions:

9.                   Place two or three equally tarnished pennies on each of four plates. Use masking tape or a sticky note to mark each plate with the ingredient you are testing (vinegar, tomato paste, salt, and water).

10.               Cover the pennies with the various ingredients and allow them to sit for at least two minutes.

11.               Rinse the pennies from each test plate with water. Much to our surprise, none of the ingredients did a good job of cleaning the dirty pennies. Where did we go wrong? Maybe two or more of the ingredients work together to react against the copper oxide on the penny.

12.               Place two or three equally tarnished pennies on each of three plates. Make three signs that say "Tomato Paste + Vinegar," "Salt + Vinegar," and "Tomato Paste + Salt."

13.               Cover the pennies with each of the mixtures and give the ingredients at least two minutes to react.
14.    Rinse the pennies under water you will find the clear winner is the mixture of vinegar and salt.
