What feels solid when you squeeze it but turns to liquid when you let go? A non-Newtonian fluid! With just water and cornflour, you and your kids can create Oobleck, a gooey, mind-bending substance that’s incredibly fun to play with—and sneakily educational too.
Kids will love poking, squeezing, and dripping the mixture, learning firsthand about properties of matter and states of change. It’s messy, it’s science, and it’s a perfect hands-on sensory experience!
Materials Needed
• Cornflour (also called cornstarch)
• Water
• Food coloring (optional for extra fun)
Tools Needed
• Mixing bowl
• Spoon (optional—hands work best!)
Steps
1. Mix the Ingredients: Start with about 2 parts cornflour to 1 part water in a bowl.
2. Adjust Consistency: Stir gently. If it’s too runny, add more cornflour; if too dry, add a little more water.
3. Get Hands-On: Encourage your child to squeeze it, tap it, and watch how it behaves differently under pressure.
4. Experiment: Try punching the surface, letting it drip, or rolling it into a ball to see how it acts!
5. Clean Up: Dispose of the mixture in the bin, not the sink (it can clog drains).
