WATCH: Make your milk come alive

It’s not often you get to recreate a chemical reaction with whatever’s lying around your house, so this experiment is pretty special.

All you need to do is pour milk into the bottom of a plate, and drop various colours of food colouring into the milk. You can put all the colours on top of each other, or arrange the drops in a circle in the centre of the milk. Once you’ve done this, drop a small amount of dish soap into the centre of the colour blots. You can even just put the end of a cotton bud into some dish soap and stick that into the centre of the food colouring. You should immediately see the milk react and the food colouring rapidly disperse to create some amazing patterns.

How does this work? Dylan at Youtube channel HouseholdHacker explains:

"Well it’s pretty simple, food colouring is less dense than the milk itself, so remains suspended within the fat molecules of the milk. The soap breaks up the fat and lets it spread across the surface of the milk. As [the fat molecules] break and expand, they create movement in the milk, and pull the colouring along for the ride."

Here's Dylan's version of the experiment:
