What happens when you combine cornstarch and water?
Cornstarch and water mixed acts both like a solid and a liquid. Cornstarch and water is a suspension mixture with a solid dispersed into a liquid. When you press the mixture quickly, the starch molecules close together. This causes the water to get trapped between the starch chains and create a semi-rigid structure.
Can you separate water and cornstarch?
The cornstarch will not stay mixed with the water indefinitely. Over time, the grains of the cornstarch will separate from the water. It will then form into a solid clump at the bottom of the plastic storage bag. For this reason, DO NOT pour this mixture down the drain.

Cornstarch should be kept covered in a cool dark place (the pantry) away from moisture. The best way to store it is in its original container with the lid re-sealed. As long as it remains dry, it will remain safe to use since the shelf life of cornstarch is really indefinite.
In what state of matter were the cornstarch and water belong?

Can oobleck stop a bullet?
The materials reminded her of Oobleck, a non-Newtonian fluid — which thickens when force is applied — made of cornstarch and water and named after a substance from a Dr. Seuss book, and she became interested in producing a material that would stop bullets without shattering.
How many ways can you make Oobleck?

Why does cornstarch hold its shape under pressure?
Most of it has to do with pressure. The size, shape, and makeup of the cornstarch grains causes the cornstarch to “lock-up” and hold its shape when pressure is applied to it. People have filled small pools with oobleck and they are able to walk across the surface of it (as long as they move quickly.)…
