Liquid Starch Slime

If you’re on the internet at all you’ve seen slime. It’s a quick easy sensory activity. And, kids love it! Plus, it’s a great way to teach kids about chemical reactions and the properties of a polymer. So, Alli and I whipped up a batch.

It only takes three ingredients, plus any additives that you want for texture, color, or aesthetic. We made a basic slime with colors and glitter.

ingredients:

1/2 cup Elmer’s glue

1/2 cup water

1/2 cup liquid starch

Optional – glitter, food coloring

ingrediants

In a bowl, mix the water and the glue together and ‘stir stir stir.’

Once fully combined, add food coloring (if desired) and stir again to incorporate. In my experience, liquid food coloring works better than gel. Alli wanted to make green, and I made mine purple.

Add glitter.

There can never be too much glitter. Pro tip: If the glitter goes anywhere other than the bowl, just use a lint roller for easy cleanup.

Now, it’s time to add the liquid starch. The reaction is quick. You’ll see the slime start to form almost immediately.

At some point you’ll have to abandon the spoon. Just keep working it with your hands until the liquid is gone.

It’s available to play with immediately.

Alli pretended to listen to me while I explained what makes slime a polymer. (It has qualities of both a liquid and a solid. Solid molecules stick tightly together, liquid molecules spread and disengage from each other. In the case of a polymer, however, they chain themselves together, and that is why we can stretch the slime).

Overall, a great indoor activity for kids of all ages. Let me know what your favorite slime recipe is!
