STEM is all about problem solving through the use of science, technology, engineering, and math.

What You Need:

  • 6 plastic containers

  • 6 paper towels

  • Food coloring

  • Water

What To Do:

  1. Set up all the containers in a circle.

  2. Pour water into every alternate container about halfway up.

  3. In the containers with water in them, add a few drops of food coloring – yellow in one, red in another container, and blue in the last container.

  4. Fold a paper towel in half lengthwise and hang it between two of the containers so that one end of the paper towel is inside the container with the food coloring and the other end sits inside the empty container. Repeat this until you use all 6 paper towels, creating a “bridge” between each of the containers to connect the circle.

  5. Ask your child to make a prediction for what will happen. Observe together as the colored water travels up the paper towels and create pools in the empty container. As the two colors drain into the same container, you’ll see the colors mix. You can talk about topics such as colors mixing and water being absorbed into the paper towel.
