Cornstarch Suspension

What Happened:

When we talk about "states" of matter, we usually talk about the three types:  solid (like a rock), liquid (like water) and gas (like the air we breath).

A mixture of cornstarch and water make what is known as a suspension.  When you squeeze a Cornstarch Suspension it really feels like a solid because its molecules line up.  But it looks like a liquid and acts like a liquid when no one is pressing on it because the molecules relax.  This is another state of matter, called a suspension (It can act like a liquid, or, when pressed like a solid.).
