This is a great way to teach children about liquids and solids. When the substance is created, it will literally change from a liquid to a solid depending on how it is handled. The best part is, it is a cheap, quick and easy (though sometimes very messy) experiment.
Oobleck is a non-Newtonian fluid. That is, it acts like a liquid when being poured, but like a solid when force is applied.
***What You Need***
- Corn Starch
- Water
- Container
- Plastic spoon
Step 1:
Place Cornstarch into containers
Step 2:
Stir in water. The ratio should be about 2:1, corn starch to water. Stir until the desired consistency is reached. Add more water if you would like to make it thinner or more cornstarch to make it thicker. I usually let the children choose which color they would like their Oobleck to be and then add food coloring. (This is a great opportunity to teach younger children about mixing primary colors.)
Step 3:
Mix everything together and start playing. Try to pick it up and make a ball. When the ball is complete, let it rest in your hand and watch what happens.
