Cornstarch Slime

If you’ve ever wondered why it might be hard to get out of quicksand, it’s because it can act like both a liquid and a solid. Cornstarch slime is a fun substance that does this too! When a substance like this has properties of both liquids and solids, they are called non-Newtonian fluids, which you’ll learn more about in this experiment. You’ll also explore what interactions make it go from one state to another. When you slowly press your fingers into cornstarch slime — stored in a Ziploc® brand sandwich bag — it’ll feel like a liquid. But when you quickly press your fingers into it, it becomes as hard as a rock! Why do you think that is?
