Room 7, 8 and 9 students carried out an experiment that showed how one end of the molecules in detergent are attracted to fat while the other end repels water. We learnt that milk is made up mostly of water, with protein and fat being two other main components. As the molecules in detergent went about their business, the food colouring in the milk moved around in a chaotic manner.
A fun experiment which demonstrates how molecules in detergent work.
