Tie-dye milk

Watch your milk turn multi-coloured!

Take a look at this video of crazy colour explosions in milk:

Go see it on youtube.

Pretty cool for something so ordinary. Here's how you can make your own 'milk art':


  • Milk, preferably full fat
  • Food colouring
  • Washing-up liquid
  • Cotton buds
  • A shallow plate or a dish

Pour the milk onto a plate, enough so that the bottom is covered.  It doesn't need to be very deep.

Add a couple of drops of different food colouring near to the centre of the plate

Dip the end of your cotton bud into the washing-up liquid

Touch the cotton bud into the centre of the plate and watch the colours explode!

Experiment with different colours, and think about:

  • What gives the best effect?
  • What happens when you touch the milk in several different places?
