Walk On Water Cool Magic Science Experiment
In this fun and easy magic science experiment, we’re going to create an interesting Non-Newtonian liquid that we can actually walk on and impress your friends.
Materials:
- Cornstarch
- Small kiddie pool or large flat plastic container
- Optional – Food coloring or washable paint
- Water
Instructions:
- File the kiddie pool or container with an inch or two layer of corn starch.
- Add about one part water for every two parts corn starch.
- Feel free to add some food coloring for fun. Just be aware this can dye skin and clothing. Another option is to use washable paint to color the mixture. Simply mix the washable paint with the water before adding to the cornstarch.
- If the mixture gets to watery, just sprinkle in some more cornstarch.
- Making sure the container is in an area that can get messy and on a very stable and level location, have the guests attempt to walk across the mixture.
- You can also set aside some of the mixture and put it in baggies for the participants to take home and enjoy.

How it Works:
While we are not actually walking on water, we are walking on a Non-Newtonian material that can have the properties of a liquid. A Non-Newtonian material can also exhibit the properties of a solid when force is applied. When we step on the Non-Newtonian, enough force is applied that it momentarily acts like a solid and allows us to walk successfully across the surface without sinking.
Make This A Science Project:
Try adding salt. Try walking at a slower pace. Try adding more water.
