Making slime is such a fun activity, once you start you’ll never want to stop!

Mermaid Slime Recipe Without Borax

Ingredients
- 1 cup Elmer’s clear glue
- 1 tablespoon baking soda
- 1.5-2 tablespoons contact solution (must contain boric acid)
- Extra fine glitter in shades of blue and green (all ours came from this 30 piece kit)
- Fine purple glitter
Instructions

Pour the glue into a large bowl.
Add the baking soda and contact lens solution to the bowl.
Mix with a fork until combined and the mixture starts to clump together.
Use your hands to knead the slime together until it forms the consistency you like. If it’s too sticky, feel free to add a tiny bit (1 teaspoon at a time) of contact lens solution then knead again.
Spread the slime out on a flat surface then shake the blue and green glitters onto of the clear slime. Mix the glitter into the slime until completely combined.

Sit back and enjoy your awesome mermaid slime!
If you’re wondering how much glitter to put into your slime, it all depends on how shimmery and reflective you want it. We added 5 different shades of extra fine blue, green and teal glitter and about 3 teaspoons of fine purple glitter.
All of the extra fine glitter we’ve used in our slime recipes comes from this glitter kit that we bought off Amazon. It’s been really awesome to have so many different choices of glitter right at our fingertips!

Hi! This looks like so much fun! How long do you think this will last in a kindergarten classroom?

Hmmm, do you mean like how long will it keep? If so, at least a week if you store it in an air tight container (or ziplock bag), but ours has lasted a few weeks without getting too stiff. Does that help?
