What State of Matter is Slime?

Slime is ooey, gooey, and so much fun to make and play with. But have you ever wondered what state of matter slime is? Let’s talk about it.

First of all, what is matter?

Anything that has mass and takes up space is matter. Even though you can’t see it or feel it, even air is matter! Small particles called atoms are made up of even smaller bits of matter, and atoms make up everything.

There are three basic states of matter:

  1. Solid. Solids are usually hard and have a fixed shape.
  2. Liquid. A liquid takes the shape of its container.
  3. Gas. Gases are in the air and have no fixed shape. They will spread out to fill their whole container.

Did you know that objects can change their state of matter? Water is a liquid, but if you freeze water, it hardens up and becomes ice, a solid. You can melt ice and turn it back into water. If you heat water up, it turns into steam, which is a gas.

Hmm… Does slime sound like it fits into any of those categories? Not really. Slime is tricky because it isn’t quite a solid, but it isn’t quite a liquid either. Luckily there’s another category for those kinds of substances. Slime is a non-Newtonian fluid – a state of matter that’s not a solid or a liquid.

In the October Winkle Crate, we made slime! To get the easy slime recipe and follow along with video instructions, click here. In the video, we’ll talk more about states of matter and the science of slime!
