Magic, or almost magical, is the effect produced by this fun experiment to try with the youngest members of your home. You only need milk, some food colouring, and bowls, (don’t worry, this doesn’t involve anything exploding!). Pour the milk into a bowl (just enough to cover the base), and then add drops of different colours. You can drip the colours randomly, or try to create a composition. Dip a moistened cotton swab into the bowl and watch the magic unfold! The chemical reaction creates a similar effect to marbling, or as we like to call it, VITROMARBLING. This is a simple experiment, completely harmless, that offers a fun distraction for children.
