Make Flubber!

Flubber Materials:


Warm water
2 cups Elmers White Glue*
Liquid Water Color (do not use food coloring)
Glitter (optional)
2 tsp. Borax (20 Mule Team Borax, available in any grocery store laundry section)


  • In a small container, combine:
    1-1/3 cup very warm water
    2 tsp. Borax
  • Stir until Borax is completely dissolved.
  • Set aside.
  • In a large container, combine:
    1-1/2 cup very warm water
    2 cups Elmer’s White Glue
    Liquid Water Color
    Glitter (optional)
  • Mix thoroughly.
  • Pour the contents of the small container into the large container.
  • Mix well using your hands.
  • Lift and turn the mixture until it is fully combined.


If flubber sticks on hair, clothes or carpet, use white vinegar to clean it. The vinegar completely dissolves the flubber.
This recipe yields enough for 6 children.
If stored in an airtight container, the flubber will last for up to two weeks.
Liquid watercolors, glitter and gallon containers of glue are available by the gallon from Discount School Supply – 1-800-627-2829

What happens to the Flubber when…

it is stretched?
it is rolled into a ball and bounced?
it is stretched over the opening of the jar?
an object (golf ball, etc.) is rolled on it?
What else can you do with flubber?
…make it and find out!

A Closer Look:

Flubber is a polymer made by a chemical reaction. Polymers are very long chains of repeating units. When the two solutions are combined, polyvinyl acetate chains (a polymer from the white glue) are linked together in a 3-dimensional arrangement by borate ions (from the Borax) and other chemical bonds. This produces the thick, sticky polymer called Flubber.
