Fill a pie plate 1/4 to 1/2 full with cream or whole milk. Do not use any other type of milk or your experiment won't turn out right. Now squeeze drops of food colouring into the milk. Make sure the drops don't touch one another.

Now take your dish detergent and pour drops of it all around the rim of the pie plate and watch the colours explode!

The cream or whole milk contains tons of tiny droplets of fat and those molecules of fat stick together so that when you drop the food colouring into the milk they actually float on top of the fat. When you drop the soap into the milk it breaks the bonds holding the fat molecules together creating spaces between the fat droplets and the colours then swirl into those spaces causing a kaleidoscope or explosion of colours. It is really neat to watch because the colours seem to bubble up from underneath other colours creating the most interesting patterns.

Enjoy : )
