Magic Milk Experiment

Math & Science

Ages: 2.5-4 years

Make your colours move! This a great interactive activity that will help build skills like observing, noticing detail, predicting, hypothesizing and critical thinking. In addition, children can practice math concepts (i.e. comparing, measuring, data collection, problem solving and so much more) – all while having fun!


  • Homogenized milk
  • Liquid food colouring
  • Dish soap
  • Cotton swabs
  • Shallow pan


Observe each step with your child.

Set-up your experiment

  1. Pour a thin layer of milk into a shallow pan.
  2. Drop a few drops of food colouring all around the milk.

Time to watch the magic!

  1. Dip a cotton swab into the dish soap.
  2. Put the soapy end of the cotton swab into the milk, press it down and hold for 15 seconds.
  3. Repeat in different areas of the dish and watch the magic!

Magic secrets

Milk is made up of minerals, proteins and fats. When the dish soap touches the milk, the fat breaks up and the soap molecules move away and try to attach themselves to other fat molecules in the milk.

At Learning Jungle, we believe all children are capable, confident and full of potential. Co-learning empowers your child to take initiative. Encouraging child participation and engaging in open-ended, thought-provoking conversation throughout play is important for healthy child development.

Conversations with your child

  • What did we observe?
  • What happened after we put the cotton swab in the milk?
  • What do you think happened?
  • What colours and shapes do you see?
  • What direction is the movement?
  • How many shapes do you see?
