Magical Goo

Sir Isaac Newton is a famous mathematician and physicist who lived from 1642 to 1727. Newton described how “normal” liquids or fluids behave. A newtonian fluid changes its viscosity only when it freezes or when it turns to a gas. Newtonian fluids also take the same shape as their containers.

Non-Newtonian fluids don’t behave this way. They are strange substances that are a solid when under pressure and a liquid when not under pressure.

I made mine with cornstarch, water, and blue food coloring. Ketchup, blood, yogurt, gravy, pie fillings, and mud are other examples.

You can mix your own by combining 1/8 cup water with 5 tablespoons of cornstarch. Then just mix and play with it with your hands. Try squishing it into a ball. Then let it go.

Even my sister thought it was cool.
