A science experiment that features a crazy-acting gooey slime? Count our little guy in! In this simple experiment, liltscientists get to play around with a super awesome non-Newtonian fluid and explore the properties of solids and liquids.

Here is what you will need:


2 cups of cornstarch

1 cup of water

Food coloring (optional)


Large bowl



Phase 1:

Get your slime ready!


Pour the cornstarch into a bowl, and then begin to add water. You will need about 1 cup of water, but you may need to add more or less. The goal is to get a consistency that has both the properties of a solid and liquid. Spoiler alert! Stirring is going to be tricky! I like to have this part done before I call the kids in.

Phase 2:

Present the slime! You can give your litlscientists tools for exploration, like spoons and cups, or you can have them just use their bare hands. Because this slime is a non-Newtonian fluid, kids will quickly discover that sometimes it behaves like a solid, and other times it acts like a liquid. This mind-boggling fact will keep them busy exploring for quite a while!


Get busy exploring!

Some good questions to ask:

What happens if you touch the slime slowly and gently?

What happens if you touch the slime very quickly and with force?

What happens if you squeeze the slime?

What happens if you hold it in your hand very gently?

What happens when you pour the slime?

Vocabulary you could introduce:



Non-Newtonian fluid- has both the properties of a solid and a liquid.
