Magic Milk Experiment

This at home science experiment is more like an art project than science! Your kids will be amazed by the colorful reaction you can produce with the magic milk experiment.

Messiness Level: Low
Difficulty Level: Easy!

What You’ll Need:

  • Milk- any kind of milk will work, we used whole milk
  • Dishwashing liquid
  • Cotton swabs
  • Food coloring
  • A tupperware or container with side to perform the experiment in

Milk, detergent and food coloring

1. After laying out all of your ingredients, pour a thin layer of your milk into the container. It doesn’t have to be super deep, you just want the milk to cover the bottom of the pan.

2. Next, drop in different colors of your food coloring. Make sure to use a variety of colors to produce the reaction.

2. Cut your lemons into halves. You want to cut them down the center- not from end to end. This will give you thicker lemon halves, and this will maximize your volcano’s reaction.

3. Take your craft stick, and poke holes in each section of the lemon.
