We poured some milk (full fat works best) on a plate and added a few drops of food colouring. Next we dipped some cocktail sticks in washing up liquid and touched the surface of the milk. The effect was instant!
The washing up liquid breaks the surface tension of the milk and allows the food colouring to flow through and the result is 'awesome' according to Kasey!
You can see what happened in our videos!
These are sooo cool!
