Make Your Own Oobleck!

Oobleck is a Non-Newtonian fluid.

What is a Non-Newtonian Fluid?

A Non-Newtonian fluid is a substance that behaves like a solid and a liquid! If force is applied to the fluid, it is turned into a solid and if force is taken off the fluid, it becomes a liquid.

How do Non-Newtonian Fluids Work?

The makeup of Non-Newtonian fluid particle are very teeny tiny and small. This means that they are very vulnerable to electrical charges. When no force is applied to them, the grains use electric force to push apart from each other. When force is applied, the charges are too weak to push apoart so they stay solid. This is how Non-Newtonian fluids work.

a cup of corn starch

half cup of water

a mixing bowl

Directions: Pour the corn starch into the bowl. Then, pour the water in. Then, mix the two substances with your hands. You can immediately feel something weird. Try to roll the Oobleck into a ball. Then, hold it out in your hand. What do you notice? Send us pictures at
