Magical Milk

A few years ago, I tried the Magical Milk experiment for the first time, and it was a blast! It’s similar to the popular Fireworks in a Jar activity, but in my opinion, even more fun. With just a few simple ingredients, kids can create stunning and colorful art on a plate of milk. Not only is it visually impressive, but it’s also a great way to teach children about the science behind the experiment. Give it a try and see the magic of science come to life!


  • Milk (Higher fat content works best)
  • Bowl
  • Q Tip
  • Food Coloring
  • Dish Soap


Pour enough milk to cover the bottom of the bowl.   Put a few drops of each of the colors in the center of the milk.

Dip on end of the Q-Tip into dish soap, then give the kids their “magic wands” and let them dip their wands in the center of the food coloring. It’s important to tell the kids to only dip their wands in the milk and NOT stir.
Then sit and watch the colors spread, swirl, and mix!  If the swirling slows down…dip the soapy Q-Tip back in the bowl.

The  Magical Milk Experiment is a fascinating display of chemical reactions and surface tension. By introducing drops of food coloring into milk and subsequently adding dish soap, the surface tension of the milk is disrupted, triggering a chemical reaction. This reaction occurs as soap molecules connect with fat molecules in the milk, prompting them to move and generate mesmerizing swirling patterns. As the reaction between the soap and milk persists, the colors keep changing and moving, creatin
