Solids, Liquids and Gases Activity for Kids
Oobleck DIY
- Duration: 15-30 min

To create a mixture called Oobleck that behaves like a liquid and a solid!

- 11 Cup Water
- 1A bowl
- 1Measuring Cups
- 1A spoon
- 1Old newspaper
- 1Towels

- 2Next pour 1 cup of water into the bowl.
- 3Now mix until the Oobleck forms, this could take a few minutes of mixing
- Tip:You may need to adjust the amount of water or cornstarch slightly to get the right consistency.
How It Works
Oobleck behaves like a liquid sometimes, and a solid at other times. If the Oobleck is pressed on, it acts like a solid and feels hard. Other times it doesn’t keep its shape and behaves like a liquid. This is because when you press on the Oobleck, the water gets trapped in between the pieces of cornstarch. The harder you press, the firmer the Oobleck becomes.
