How you ever wanted to remove rust? Well Olive asked which acidic liquid can
remove coin rust better in three days.
She compared distilled white vinegar and Coca-Cola. Olive had to research all about PH
levels. She even found out that
phosphoric acid is put in Coca-Cola to give it that tangy flavour. Olive did a marvelous job on this experiment. She took photos of the coins and display
board was awesome. Olive found out that
Coca-Cola removed the rust the fastest.
Thanks Olive, I think you have inspired people to rethink about drinking
Coca-Cola as if it can remove rust from a coin then imagine what it is doing to
your insides!
