Let’s Make Oobleck!
Oobleck isn’t a liquid or a solid. Making Oobleck is a great science experiment to show how changes in pressure can change the properties of some materials. What happens when you press down on the Oobleck or slowly run your fingers through the mixture? If you want to pair this activity with a book, you can read the Dr Seuss book, Bartholomew and the Oobleck.

Ingredients:
- 1 cup water
- 1.5 – 2 cups cornstarch
- a few drops of food coloring – optional
Instructions:
- Pour water into a large bowl
- Begin adding cornstarch to the water. You can stir with a spoon at first, but you’ll need to use your hands as the mixture thickens.
- Once you’ve added the initial 1.5 cups of cornstarch, add the remaining amount a little at a time. You may not need it all.
- You are looking for a consistency that is liquid and solid at the same time. (When you press down the Oobleck should feel hard but when you run your fingers through the Oobleck it should feel like a liquid.)
- If you find you’ve added too much cornstarch, add a little more water to thin it out.
- Have fun!
