Whip Up Some DIY Slime

Treat your Halloween party guests to their very own slime-making fest.

I think kids and slime go hand in hand. There has to be something about squishing a sticky and gooey mass of sludge between your fingers. I think it’s a great stress reliever for adults too. My kids have been slime fanatics for as long as I can remember. I thought it would be fun to celebrate Halloween with a get together that included kids being able to take home their own jar of customizable slime. I gathered fake spiders, cockroaches, food coloring and glitter and set them free to create.

As I was researching making slime, I realized that some folks were nervous about using Borax. I was happy to learn via various science sites, when white glue (polyvinyl acetate) is combined with Borax (sodium borate), it undergoes a chemical reaction that changes the glue and Borax into an innate substance. The same slime ingredients used in this post are also used to make rubber balls and even tires for cars. How cool is that?

To make slime you will need:

(makes 1 serving of slime)

  • Borax powder (1/2 teaspoon)
  • white craft glue (1/4 cup)
  • water (1/2 cup)
  • 2 bowls
  • 2 spoons
  • food coloring
  • glitter, fake spiders, eyeballs, cockroaches etc.
Water is combined with glue in a bowl.

In one bowl, combine 1/2 teaspoon of Borax with 1/4 cup of water. Mix well and set aside to dissolve. In the other bowl, combine 1/4 cup of glue with 1/4 cup of water. Stir until well combined.

The water and glue is mixed.

Next add food coloring to your water and glue mixture and mix it well. If you are using glitter this is the time to add it.

Slowly add the water and Borax mixture to the glue mixture stirring constantly. It will begin to thicken. Add the water and Borax mixture to the glue and water mixture until you are satisfied with the slime consistency. 

The slime begins to form.

Note: If you are concerned with any remaining Borax on the slime after the reaction with the glue, simply rinse it off with water. If the Borax still concerns you, then check out other online slime recipes that substitute baby powder, laundry detergent and cornstarch in place of the Borax. This slime is not edible and should not be ingested. This slime may stain or permanently slime clothing, rugs and furniture, so please supervise its use.
