How to Make Slime with Baking Soda (no borax!)

Save this idea for later!

1.2Kshares

Want to learn how to make slime with baking soda? Follow along with this easy tutorial to make baking soda slime without borax!

Slime is one of my kids’ favorite things. They love the stretchy, gooey, and fun (as well as STEM learning) that slime provides.

We’ve made a lot of slime recipes, and we almost always make slime for any upcoming holiday just for fun.

Borax and liquid laundry starch are the two most common thickeners for slime, but some kids (and adults) are sensitive to Broax (laundry starch also has Borax in it).

What is a good substitute for borax when making slime? This baking soda slime teaches you how to make slime with baking soda and water and makes a wonderful borax alternative slime. Slime for sensitive skin is possible with this baking soda slime recipe! #slimerecipes #slime #kidsactivities #stemactivities

A borax reaction can cause itchy, dry, red, and peeling skin. For kiddos with more sensitive skin, alternative slime recipes must be found (like this delicious taffy slime or magnesium slime!) and this slime with baking soda.

We made a version of slime that uses baking soda as the thickener, and the kids loved it.

This baking soda slime is a little messier than traditional slime, but it’s a blast to make a play with and you don’t have to worry about it irritating the skin.

Baking Soda Slime Science

Traditional slime is made when boron mixes with the polymer chains in the glue, creating strong, but flexible bonds between the molecules. But slime made with baking soda is a little different.

When you learn how to make slime with baking soda, you’ll find that the ingredients in the baking soda bond with the glue to create a slime that is softer, stretchier, and a bit stickier than traditional slime.

However, because most kids don’t have any sensitivities to baking soda, you can use it even with toddlers and preschoolers who might put the slime in their mouths.

It won’t taste good, but the non-toxic slime ingredients won’t hurt the kids at all.

If this is your first time making slime, you should follow along with our post on slime troubleshooting. 

Liquid laundry starch slime made with clear glue is the easiest slime recipe, but the baking soda slime recipe is pretty easy to make too!

If you don’t want to waste a lot of ingredients, try mixing up a small batch first to make sure you won’t have to tweak it before you make the larger version.

We always stock up on gallon sizes of glue and the large laundry starch just in case something goes wrong (but it almost always goes smoothly).

You will want to make sure you’re making this slime on a tray or plate, to have something to catch the slime.

Don’t make the slime anywhere near the carpet, and make sure kids are wearing old clothing that you don’t mind washing.

If you do get the baking soda slime in hair or clothing, it will wash right out with warm water and soap.

A trip through the regular washing machine cycle will get slime right out of most clothing.

And getting it out of hair is as simple as washing with shampoo and conditioner.

HOW TO MAKE SLIME WITH BAKING SODA

can you make slime with baking soda

This slime recipe with baking soda is not quite as stretchy as traditional Borax slime.

In fact, it reminds me of the gooey slime that Nickelodeon would always dump on people.

The nice thing about this slime, however, it that it is SUPER easy to clean up out of clothing and the carpet.

However, we recommend playing with it at the table and not around carpet or furniture.

This slime is perfect for using as a writing tray, or just for sensory, messy fun.

Kids will love the sticky, gooey texture of this slime. My preschooler especially loved the squelchy sound it made when she squeezed it between her fingers.

When your slime starts to get runny again, add more of the baking soda water to turn it back into slime.

The baking soda slime recipe does not last as long as some other slime recipes, but it’s easy to clean up and kids who are sensory seekers will love the sticky and gooey feeling more than that of a few other slime recipes.
