Our Coin Cleaning Experiment

The coins in our café were not shiny. Mrs Husbands suggested that we could clean them with ketchup!!


Emily thought we should put them in water and scrub them. Lucas suggested that we needed soapy bubbles and Thomas thought hot water would be better than cold.


We set up our experiment with ketchup, hot water, hot soapy water and cola as well.


Then we waited…






Can you see which worked the best to clean the coins?
