Tie Dyed Milk

Tie Dyed Milk:

Using just a few things in your house, you can make your own tie dyed milk! You’ll create some beautiful, colorful patterns that swirl around in your plate.

All you need for the tie dyed milk activity are:

  • Milk
  • A plate
  • Food coloring
  • One Q-tip
  • Liquid Dish Soap
Gather your items together:

Next, pour the milk into the plate. Make sure you have enough to just cover the entire area (you don’t need to pour in too much).
Carefully add three drops of food coloring into the middle of the plate. We used red, blue, and yellow:
put in a few drops of food coloring
Take your Q-tip and dip one end into the liquid dish soap. Carefully place the soapy-end of the Q-tip into the milk, where the food coloring is:
soak the q tip in dish soap
You will see something AMAZING happen!  Try it!
put the q tip in the middle of the food coloring and watch what happens!

How does it work?

The dish soap that you put on the q-tip does not mix with the milk. Instead it floats on top and spreads over the surface. As it spreads, it attracts the food colouring. Dish soap is a “degreaser” so the molecules in it are attacking the fat in the milk, causing motion which creates the swirling of the colors. When two colors meet, they mix to create the beautiful colorful patterns you see.

Since the dish soap attracts to the fat in the milk, try this experiment again but use the fat in the milk as a variable. Try it with non-fat milk, 2% milk, and then whole milk. How does the fat content affect the swirling patterns. Do the colors swirl with more fat in the milk or less? Post your results in the comments below!
