Borax Silly Putty


You will need:

PVA glue (this is woodworking glue)


food coloring

hand lotion

borax (available at grocery stores)


disposable cups

Please have an adult's supervision for this activity.

We’re going to make a simple plastic that can bend, stretch, and even bounce. It can also take imprints from the newspaper comics.

Borax comes from the rock called Kernite. Kernite is used in the production of boric acid and borax. Boric acid is used in the production of textile fiberglass (cars, boats, circuit boards, roofing shingles), ceramics (glazes), chemicals (corrosion inhibitors, insecticides, pharmaceuticals), and specialty glass (heat resistant glass, laboratory glass). Sodium borate, a white, anhydrous, crystalline salt with an alkaline taste; it is used as a flux in manufacturing of glass, soap, enamel and artificial gems. Several borate ores, including borax, colemanite and ulexite, can be found at the U.S. Borax mine near Boron, California’s largest mine. The mine supplies nearly half the world’s demand for refined borates. 

Place about ¼ cup PVA wood glue in a disposable cup. Add a drop or two of glycerin, a drop of food coloring, and a teaspoon of hand lotion and stir.

In a separate large container or bowl, add borax to warm water. Keep adding borax until there is about 1/2 cup of undissolved borax until there is about ½ cup of undissolved borax in the bottom of the container. Pour about ¼ cup of this solution into the glue mixture.

Stir mixture with an old spoon. The mixture will soon begin to look stringy. When this happens, pour in ½ cup more of the borax/water solution and stir. As the plastic begins to form, it will turn into a soft glob that the children can pick up with their hands. Squeeze and play with the glob in the solution until it holds together in the shape of a ball.

Try bouncing it and using it to pick up the imprint of comics from the newspaper.
