Fidget spinners may be taking over classrooms (at least in schools where they haven’t been banned), but that doesn’t mean slime has gone away. Slime is still in the spotlight! However, a growing number of parents are concerned about potential rashes and reactions to Borax, a common slime ingredient. Have no fear; this is a Borax-free slime recipe!

It’s easy to make slime without Borax, just substitute in laundry starch.
- 1/4 cup liquid starch
- 1/2 cup white glue
- One liquid measuring cup
- One medium or large mixing bowl
- A spoon or fork for mixing
- Optional add-ins like food coloring or glitter
- Pour glue into a mixing bowl.
- Add optional mix-ins.
- Pour the liquid starch into the glue mixture.
- Stir the mixture. It will get quickly get gloppy. It may seem like you have too much liquid, but keep stirring.
- When you feel like you can’t mix any further with your spoon, finishing mixing the slime by hand. It may feel watery at first, but it will firm up as you smoosh and knead it for a minute.

Put Your Slime to the Test
Investigate the properties of the slime. Is it brittle or elastic? How does it feel in your hands and between your fingers? Will it bounce off of hard surfaces or stick to them? Create a list of adjectives that describe the look, feel and properties of the slime.
The slime can sit, loosely covered, on your counter for several days.
Dispose of the slime in your trash bin, rather than down your drain, so that it won’t muck up your pipes.
The Science Behind the Slime
The white glue is a polymer, that is, a long chain of molecules. When you mix it with the liquid starch, you cause a chemical reaction in which the many polymer strands link together. Further your knowledge by reading more about the chemistry of slime.
