Teach your students about capillary action with this fun and easy-to-do science experiment. Walking Water uses low-cost materials with a dramatic result. All you need is paper towels, water, jars, and food coloring.
Students will be amazed to see how the water moves from one cup to the other. First, it moves uphill! And the empty jars begin to fill with water!
If you use primary colors, as I did, the colors in the middle will be the secondary colors.
The set up for this science experiment is easy to do and uses just a few materials.
