The Experiment

My son's homework is getting far more complex. He is only primary 1. We were to carry out an experiment to see oil float on top of water and see salt sink to the bottom and then blobs of oil float to the top again. It would have been far better if I had food colouring but I don't have stuff like that. I'm not a baker. However it turned out ok and it was good to see my son amazed.
