Magic Milk Experiment

Today we had lots of fun doing a science experiment. We poured some full fat milk in a dish with some food colouring. We then got a cotton bud and dipped it in some dish soap (Fairy washing liquid). This cotton bud was then placed in the milk, we saw a very cool reaction. We learnt that the dish soap breaks down fat. What we saw was the dish soap molecules chasing the fat molecules to break them down. We thought this looked quite like a witch’s brew. We repeated this experiment using slimline milk and the reaction was not as great as there was less fat.   to
