Flubber

Flubber 1

Materials

  • Elmers Glue (8 oz bottle of Elmers Glue-All)
  • Borax
  • Large mixing bowl
  • Plastic cup
  • Spoon
  • Measuring cup
  • Food coloring
  • Water
  • Paper towel
  • Zipper-lock bag
  • Water

Directions:

  • This recipe is based on using a brand new 8 ounce bottle of Elmer’s Glue. Empty the entire bottle of glue into a mixing bowl. Fill the empty bottle with warm water and shake (okay, put the lid on first and then shake). Pour the glue-water mixture into the mixing bowl and use the spoon to mix well.
  • Add a drop or two of food coloring.
  • Measure 1/2 cup of warm water into the plastic cup and add a teaspoon of Borax powder to the water. Stir the solution – don’t worry if all of the powder dissolves. This Borax solution is the secret linking agent that causes the Elmer’s Glue molecules to turn into slime.
  • While stirring the glue in the mixing bowl, slowly add a little of the Borax solution. Immediately you’ll feel the long strands of molecules starting to connect. It’s time to abandon the spoon and use your hands to do the serious mixing. Keep adding the Borax solution to the glue mixture (don’t stop mixing) until you get a perfect batch of Elmer’s slime. You might like your slime more stringy while others like firm slime. Hey, you’re the head slime mixologist – do it your way!
  • When you’re finished playing with your Elmer’s slime, seal it up in a zipper-lock bag for safe keeping.

Caution! This is a great way to pass and keep germs in your classroom! Solutions… clean hands, limit times uses, make individual flubber for each student… so on.
