Flubber is a rubbery and gooey substance that has nothing whatsoever to do with rubber, with absolutely no practical use at all and will definitely not help you bounce and jump high as depicted in the movies! Making flubber is a great craft project or vacation activity for children, who anyway enjoy mucking with gooey and slimy substances. Read through the instructions listed below to learn how to make flubber with your children as a family activity.
- A 4 oz bottle of Elmer's Glue-All
- Food coloring
- 1 teaspoon of 20 Mule Team Borax
- Warm water
- 2 mixing bowls
- Wooden spoon or spatula
- Poster paint, glitter (optional)
Prepare the glue. Pour the contents of the glue bottle into an empty bowl; rinse the bottle with warm water to clean out glue from the bottle. Add ten drops of food coloring - green or any other color you like and mix the glue and coloring well using the wooden spoon. Optionally, you can use poster paints in place of the food coloring, but remember that paint can be toxic. Add glitter to give the flubber some interesting texture.
Prepare the borax. In another bowl, add one teaspoon of 20 Mule Team Borax and dissolve it in one cup of warm water. Stir thoroughly until no powder residue is left.
Mix the glue and borax solutions. Stirring continuously with the wooden spoon, pour the glue mixture into the bowl containing the borax mix. Once both ingredients are properly mixed, it will turn into a thick glob. Knead the glob until it is smooth and dry. The flubber is now ready. If you want thicker flubber, add more borax, decrease the amount of borax if you want it slimier and more fluid.
Storage and use. You can store the freshly made flubber in an air-tight container or in a Ziploc pouch. Make sure your children do not put the flubber in their mouths or rub it on their skin or eyes. Supervise carefully if the children are making the flubber by themselves.
Making flubber is a very simple process, with only two active ingredients required. It is a project the entire family can participate in and you can experiment with various colors and with the consistency of the flubber you make.
