Is it a solid? Is it a liquid? No, it’s Super-Goo! The only thing it isn’t is a gas!
all you need is
• Cornflour
• Water
• A small cup
• Bowl
1. Add 4 small cups of water to 7 small cups of cornflour in a bowl
2. Mix it around with your hands until it becomes a gooey mixture.
3. Plunge your hands right into the mixture and then lift them upwards so that the mixture drips through your fingers.
4. Grab some of the mixture and quickly roll it into a ball using the palms of your hands.
5. Slap and prod the mixture in the bowl.
science
Isn’t this mixture the strangest stuff you’ve ever seen? When you let the mixture drip through your fingers, it behaves like a liquid. Yet when you roll the mixture and slap it, it behaves like a solid. But when you stop rolling it, the mixture drips through your fingers like a liquid again!
This can mean only one thing. The mixture is both a liquid and a solid. When it is left alone, it flows like a liquid. But when you treat it roughly by slapping it or rolling it, you are forcing the water molecules into the cornflour particles and it behaves like a solid. When you stop applying pressure, the molecules can relax and the material flows like a liquid again.
