Nothing says Valentine’s Day like pink and glitter. Mix them both in this fun Valentine’s STEM activity making pink glitter slime!
Valentine’s Day is such a fun holiday. There are so many fun crafts, activities, and yummy treats to eat. But you can also make the holiday educational!
This year, we’re completing a lot of Valentine’s STEM activities to add a science twist to our holiday. We loved making this glitter slime and it was so easy, too!
Valentine Glitter Slime: A Valentine’s STEM Activity for Kids!
A lot of parents are afraid of using Borax because it can be irritating on the skin and may have other health dangers as well. We love our Borax slime, but for this slime recipe, we decided to try using something else as our sliming ingredient. Last October, we made slime using laundry starch, and that is what we used for this slime as well.

What you’ll need to make Valentine glitter slime:
Elmer’s Liquid School Glue, Premium Clear, Washable, 1 Gallon, 1 Count – Great For Making SlimeFood Coloring Liqua-Gel – 6 Color Rainbow Kit in .75 fl. oz. (20ml) BottlesPurex Sta-Flo Liquid Starch, 64 OunceOriginal Stationery Arts and Crafts Glitter Shake Jars, Extra Fine, 24 Multi color Set
- Liquid starch (we buy the huge bottles)
- Pink glitter glue (or choose your own favorite color)
- Foam conversation hearts (optional)
Mix 1/2 a cup of water with 1/2 a cup of glue. It takes a while for glitter glue to mix with the water, but we found that using a fork helps mix it properly.
Pour 1/2 a cup of Liquid starch into a container. Add the glue to the starch and stir with a fork. At first, the slime will be really sticky, but after a few minutes of stirring, it will loosen up and you will be able to handle it without it sticking everywhere.
We love liquid starch slime over other kinds of slime because it is stretchier than Borax slime and just more fun to play with!
After playing with the slime alone, Bo started to drop our foam hearts into it. They sunk into the slime, then she had a lot of fun fishing them out and hiding them again.
Valentine Glitter Slime Science
Slime forms when the glue and the starch mix and create a stretchy polymer bond. All slimes have polymer bonds that allow them to stretch rather than break like other types of chemical bonds.
