How to Make Goobeldy Goo

Your science teacher would call this ooey, gooey gunk a polymer. Your mom might call it messy. We call it fun!

You will need

  • A new 4 oz. bottle of white glue
  • 2.0 mixing bowls
  • Water
  • A large spoon
  • Food coloring
  • 2.0 measuring cups
  • Borax
  • A measuring tablespoon
  • A resealable plastic bag

Step 1 Squeeze glue Squeeze the entire bottle of glue into one of the bowls.

Step 2 Add water Fill the empty glue bottle with water, shake, and pour that in with the glue. Stir well.

Step 3 Add food coloring Add a few drops of food coloring to the glue mixture and stir. Set aside.

Step 4 Mix water & borax In a liquid measuring cup mix one cup of water with one tablespoon of borax until the borax all dissolves.

Step 5 Add borax solution Measure out one-third cup of the borax water solution, and pour it into the other bowl. You won’t need the leftovers.

Step 6 Pour & stir Slowly pour all of your glue solution into this bowl, and stir while pouring.

Step 7 Squeeze & knead The slime will start forming immediately. When you’ve added the glue mixture and stirred it, pick up the blob that’s now in your bowl and start squeezing and kneading it. There will be some water left in the bottom of the bowl.

Step 8 Gross out friends The more you play with the slime, the firmer and drier it’ll get—but it’ll still be icky enough to gross out your friends.
