Your Challenge: Stretch your mind and learn chemistry by making Funny Putty! Funny Putty

Materials: 

1/4 cup white glue

1 teaspoon household borax

1 cup water

8 oz paper cup

Wooden stirrer

Here’s How:

  1. Dissolve the borax in the cup of water.
  2. Pour the glue into the paper cup.
  3. Add 1/4 cup of the borax water to the glue, and stir really well.
  4. The glue turns into a blob! Pick it up with your hands, and start kneading it and stretching it.

Take It Further:

Add food dye and glitter to create fun colors for your funny putty!

 

How It Works:

The borax acts as a cross-linking agent or “connector” for the glue molecules. As the glue molecules become larger, after being linked, they become polymers. Thus, the solution begins to thicken and gel.
