Chemical reactions: penny turn green ( free, Chemical reactions are always surprising for kids to observe! in this science activity we'll be turning a penny green (similar to what happens to the statue of liberty!). Vinegar salt penny cleaner - weird science kids, In this fun and exciting science experiment we will create a chemical reaction that will clean dirty old copper pennies and make them shine like new! we will learn.
