Slime, Goo, and Goop

You're about to make something fun and icky, so you know what's coming first. 

STOP!!! These icky recipes are NOT food and should be made only with the help of an adult. Do not make these on your own or we'll both get in BIG, BIG trouble! Got it? Okay.

One more warning: slime, goo, and goop can get in hair or on clothing, so be careful and don't stick it anywhere you don't want it.


There's a ton of cool ways to make slime even if you don't have your own slug farm, but here's one recipe I like:

  • 1 cup Elmer's or other white craft glue
  • 1 cup water
  • 1/2 teaspoon borax (find it near laundry detergents in the grocery store)
  • 1 large Ziploc bag
  • food coloring (optional, if you want colorful slime--I like green best!)
Put on old clothes and wash your hands first. You want clean slime, you know. :)

In one bowl, mix the glue, 3/4 cup of water, and a drop or two of food coloring (if you want it). In a second bowl, stir the borax to dissolve it in 1/4 cup of water. Add this to the glue mixture. It might be pretty clumpy, so you'll have to dig in for the next part.

With clean hands, knead the slime until it's totally mixed. This could take about 10 minutes. The slime will ooze well between your fingers when it's done. To make it even slimier, just work in a little more water. 

Now play! But always wash your hands when you're done.

Note: You can keep your slime in a sealed Ziploc bag in the refrigerator. It should last for a couple weeks and won't go bad, but throw it out if you see any mold growing.


Goo is a second cousin twice removed of slime. It's not quite as much fun at parties, but it's even easier to make.

  • water
  • small box of cornstarch
Get out a shallow bowl or tub (a popcorn bowl would be good), and spread out some newspaper under it.

Dump the small box of corn starch into the tub. Add a few teaspoons of water, and dig your hands in. If it doesn't feel wet enough to shape between your hands, keep adding spoonfuls of water until it feels just right. When there's enough water, the goo will harden when you squish it hard in your hands, but it will melt away when you open your hands again.


Goop is like slime, but it's not as sticky.

  • 4 ounces Elmer's or other white craft glue
  • 1/4 cup water
  • 1/4 cup cornstarch
  • 1/2 teaspoon borax (find it near laundry detergents in the grocery store)
  • food coloring (optional)
Put on old clothes and wash your hands first.

In a small bowl, dissolve the borax in water. Add several drops of food coloring to the water if you want colorful goop. In a larger bowl, stir cornstarch and glue together until they are mixed well.

Pour the borax water into the large bowl and mix for 2 minutes. Knead the goop with your hands until it's not very sticky anymore. If it's still too sticky, mixing in a little extra corn starch should help.

Play with it! Wash your hands when done.

Like the slime, you can store this in a Ziploc bag.
