Friday Freebie: Making Cornflour Gloop

Cornflour Gloop (some know it as "oobleck") is an amazing substance known as a colloidal solution. Colloidal solutions are mixtures of fine particles (cornflour) with water that are very peculiar! When cornflour gloop is under pressure (such as if you press on it with your hands) it feels like a solid but as soon as you stop pushing on it turns back into a liquid.

Great fun, a little science and a lot of messy play opportunities! Happy Friday!
