How Does Slime Form?

Learn how to make an ocean slime recipe without borax right here! Just 3 ingredients and you'll be swimming in island life in minutes!

Slime forms through a chemical reaction that occurs when the laundry starch mixes with the molecules in the glue. The chemicals in the laundry starch cause the polymers in the glue molecules to link up, creating what’s known as “polymer chains.”

These chains link together with flexible bonds that allow you to stretch and play with the slime. Most flexible plastic products are made up of polymer chains as well.

Directions to Make Ocean Slime Without Borax

We have an ocean slime recipe with borax. But one thing that’s a bit frustrating about borax slime recipes is that they are stiff and it’s hard to control how much borax goes into the slime.

This means that the slime can often become stiff and crumbly and not really “slime-like.” And who wants that?

So this time around, we made an ocean slime recipe without borax.

Here’s how to do it:

Mix 1/2 a cup of clear glue with blue food coloring. You can add glitter if you like, but we didn’t this time.

Next, add in 1/4 of a cup of liquid laundry starch. We like using liquid laundry starch because you don’t have to add any additional water to your slime recipe.

Mix the slime until it is smooth and stretchy. If it is still sticky, you can add more laundry starch.

If your slime gets too runny, too stiff (which it shouldn’t with this borax-free slime recipe), or too stringy, check out the slime troubleshooting guide for how to fix common slime problems.

We decided to add some rocks, a volcano island, and a beach umbrella to our ocean slime. The kids had a lot of fun burying and uncovering the little toys from the ocean slime.

When you’re done playing with the ocean slime, you can put it away in an airtight container in a cool, dry place.

Slime will keep in an airtight container for about a week, but after that, it starts to get sticky. You can add more activator to make it less sticky. At this point, it’s better to use borax than laundry starch to revive slime.
