All you need is a saucer of milk, a few drops of food colouring, a couple of cocktail sticks and some liquid hand wash. Drop the food colouring into the milk, dip the end of the cocktail stick into the hand wash and then gently touch the cocktail stick to the centre of the food colouring and watch the magic as the detergent breaks the surface tension and the colours spread out.
