Make Green Flubber!

Make Green Flubber!
Go green this St. Patrick's Day and make some "Flubber" with your homeschooler! This activity is not only holiday themed, but it is also educational and super fun! Be sure to have your child record his or her hypothesis, observations and even draw pictures to document the study. Remember to observe the younger homeschool crew- this is not edible!


2 cups of Elmer’s White Glue
3 cups of warm water
1 box of "20 Mule Team Borax"
Green food dye or food coloring


1. In a large bowl combine and mix 1 ½ cups of the warm water and 2 cups of the Elmer's white glue.

2. Add a few drops of food coloring.

3. Mix this thoroughly!

4. In a smaller bowl combine 1 1/3 cups of the warm water and two teaspoons of the 20 Mule Team Borax. *Level spoonful-measured by an adult is preferable.

5. Dissolve the Borax completely, mix well.

6. Combine the glue and borax mixtures now.

7. Mix all ingredients well, you may need to use your hands, and do this until all the liquid is absorbed.

8. Children, with observation can help mix and squish this unique substance, and rubber gloves are an option for children with sensitive skin.

9. Add additional green food dye or coloring if desired.

10. Store the "Flubber" in a plastic and air-tight container at room temperature.

*A few "Flubber" notes- this recipe makes enough for 4-6 children to experiment with. Vinegar will remove the "Flubber" substance from many materials, such as clothing and hair.

Discuss with your child how the "Flubber" works- and that a polymer is made in this chemical reaction experiment. Teach your homeschooler about how polymers are very long chains of repeating units. Specifically, when they are combined, a polymer from the white glue is linked with the borate ions from the Borax, and other chemical bonds are formed. This produces the dense and sticky polymer we call "Flubber"!

Here are some additional green and "Flubber" tie-ins for your lucky and sticky lessons:
