How does slime form?

The glue is made of a polymer, when boric acid is added, the borate ions react with the hydrogen bonds, and they link together to form a NEW polymer. Cool right?

Here are some of the best books for kids that are all about bears. They're the star of the books, and are so much fun to read about!


  • 2 6-ounce bottles of clear Elmer's glue
  • 1 1/2 tbsp contact lens solution (w/boric acid)]
  • 1/2 cup warm water
  • 1/2 tsp baking soda
  • 1 1/2 tbsp glitter in white, silver, or iridescent
  • Heart confetti


  1. Add the glue to a large bowl.
  2. Add the water to the bowl. If using glue bottles, add water to bottles and shake to ensure you get all of the glue out.
  3. Add the baking soda and mix thoroughly.
  4. If using glitter or confetti add them in and mix.
  5. Add small amounts of the contact lens solution and stir consistently. (see notes)
  6. Remove the slime from the bowl leaving the liquid behind and knead it to bring it together. It is ready to play with when it is no longer sticky.
  7. Store in an airtight container in the fridge to keep fresh.


Regular glue will require less contact lens solution than glitter glue.

Add the contact lens solution slowly, mixing between additions, and add only enough to bring the glue together into a soft ball.
