Kitchen Science: Rainbow Milk Color Mixing Experiment from Creekside Learning

This easy, fun experiment is about mixing colors and making a rainbow. Using the pipettes is a great way to strengthen fine motor skills.  We used two simple ingredients for our 5-year-old Science Class of two: Milk and food coloring. The milk makes the colors so vibrant!

Kitchen Science: Rainbow Milk Experiment

You will need: 

  • 6 test tubes for each child
  • Milk, 1 c
  • 3 small jars or glasses
  • Pipettes
  • Food coloring in primary colors: blue, red, and yellow
  • Something to stir with (we used chopsticks)

First, we poured about 1/3 cup of milk into each of our 3 jars and added 1-2 drops of food coloring to each jar to make the primary colors: red, yellow and blue. This will be used to make the remainder of the rainbow colors.

Next, the kids used the pipettes to fill a test tube each with red, yellow and blue.

Then we used our chart to figure out how to make orange, green and purple.

We mixed colors in the test tubes until we got the ones we wanted. It was fun to shake and mix them up.

Then we put them in rainbow order.
