It’s alliiiiiiiveeee!

Slime is a fun and interactive way to teach kids about chemistry. There are hundreds of slime recipes out there, which produce slimes with different qualities.

In this article, we’re talking all about slime: what it is, how to make it, and what you absolutely need to know to make the best slime of all time.

We promise, we won’t do that rhyme again.

 

What Is Slime?

Slime is a sticky, gooey substance that’s fun to touch and great to use for teaching about viscosity and chemical reactions.

When kids make slime, they can learn about how different chemicals react with each other to create something new. They can also learn about how adding different amounts of different ingredients affects the viscosity (thickness) of a material.

There are hundreds of slime-based toys out there, but the best way to really get the most out of your slime is to make it yourself!

 

How to Make Slime

Learning how to make slime is simple!

You can make slime with tons of different ingredients: glue, borax, yogurt, water, cornstarch. Even shaving cream!

Whatever recipe you choose to go with, make sure you have a mixing bowl and spoon on hand. You may also need some paper towels or cloth towels on hand to mop up spills. But don’t be afraid to get messy! That’s part of the fun.

Without further ado, here are our three favorite slime recipes.

 

Recipe #1: How to Make Slime Without Borax

This recipe makes about two cups of slime.

INGREDIENTS

  • 2 (4-ounce) bottles washable school glue, such as Elmer's (see note for variations)
  • 1 to 2 drops liquid food coloring (optional for adding some fun)
  • 1/4 cup glitter (optional for adding some fun)
  • 1 teaspoon baking soda
  • 2 to 3 tablespoons saline solution (i.e., contact lens solution), divided
  1. Color the glue (optional): Pour the glue into a medium bowl and stir in the food coloring and glitter, if you want your slime to be extra exciting.
  2. Add the baking soda: Add the baking soda to the glue mixture and stir until smooth.
  3. Add the contact lens solution: Pour in 2 tablespoons of the contact lens solution and stir slowly. The mixture should begin to harden, becoming stringy.
  4. Mix until a ball of slime forms.
  5. Pick up the slime and knead between your two hands, until smooth. If the slime is particularly slimy, work in another 1/2 tablespoon of contact lens solution as needed.
