-
Put half of the corn starch in the bowl.
-
Add half of the water to the bowl.
-
Begin mixing the two ingredients until combined.
-
Add the rest of the corn starch.
-
Slowly add more water while mixing.
-
When you achieve a slime-like consistency, stop adding water.
-
If done correctly, the fluid should act as a solid when you apply pressure and return to a liquid when you let go.
-
Have fun molding your Non-Newtonian fluid!
-
As you play with the fluid, it will begin to dry out, so you may need to add some more water.
10. To keep it moist, store the fluid in a plastic bag.
Most liquids like water or molasses take the form of their containers; however, there are some exceptions to this rule, which we call Non-Newtonian fluids. These are substances that when you apply pressure to them act like solids. When you mixed the corn starch and the water, you created one of these special fluids, which is why the mixture would hardened when you squeezed it and turned back into a liquid when you released pressure.
