Slime is a fantastic tool for sensory play, as part of an anti-anxiety kit, and to develop fine motor strength. It can also be used in a lot of amazing slime STEM activities!
The Science of Slime
Slime involves chemistry! Chemistry is all about states of matter including liquids, solids, and gases. It is all about the way different materials are put together, and how they are made up of atoms and molecules. Additionally, chemistry is how these materials act under different conditions.
Baking Soda Slime
Borax and liquid laundry starch are the two most common thickeners for slime, but some kids (and adults) are sensitive to Borax. 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.

How to Make Slime with Baking Soda
What you’ll need to make slime with baking soda:
- Mix 1/4 of a cup of baking soda into two cups of warm water and set aside.
- In a second bowl, mix 5 ounces of Elmer’s clear glue (it must be the clear glue) and your chosen color
- Pour the glue mixture into the bowl of baking soda water.
- The slime will start to form little balls in the water. Fish these out, and you’ve got slime.
- Work the slime between your fingers to create a slimy, sticky texture.
- If you want to be able to pick it up without it sticking to your hands, dip your fingers into the baking soda mixture.
- You can also add the slime back into the baking soda water if it loosens up too much.
- When your slime starts to get runny again, add more of the baking soda water to turn it back into slime.
