what do you think will clean a dirty penny?

Question

another science project, need your hypothesis, we are using coke, soapy water lemon juice and bleach, which do you think will clean the penny best?

Answer 1

Coca Cola....

Answer 2

I think the coke will work best. It has been proven so many times, over traditional cleaners, that coke works best. Soapy water harldy works, just cleans off dirt. Lemon juice doesn't work at all!!! And bleach works... but not the best.

My money is on the coke!!

Answer 3

I think the coke. We did an experiment when I was in high school, and we actually cleaned a rusty penny with Taco Bell hot sauce. Needless to say, I never ate there again.

Answer 4

The carbon in the coke will probably clean it the most. The reason I say that is because I heard coke can dissolve bones in a matter of a week.

Answer 5

Get a pitcher of vinegar or lemon juice. upload usual table salt and combine. The salt will react with the acid and style a gentle hydrochloric acid. positioned the pennies in for round 5 minutes and then wash them off.

Answer 6

probably lemon juice. FYI the best penny cleaner is hot sauce. Try it!

Answer 7

In my science class we used lemon juice and salt. Good luck!

Answer 8

I used a brass cleaner not sure what is in it but an old penny looked like new.

Answer 9

Taco Bell Taco Sauce.
