This is flubber. It's a compound made of borax, water and glue. It's stuck between being a solid and a liquid. It's called an elastomer or a polymer. When you mix the ingredients together, the borax reacts with the glue molecules, causing them to link together in long strands. The molecule strands slide past each other easily, making it flow like liquid, but some of the molecules stick together to form a putty-like material.
Here's the recipe:
Mixture #1: 3/4 cups warm water 1 cup white glue (elmer's school glue) Food coloring or liquid watercolor
Mixture #2: 1/2 cup warm water 2 tsp. borax powder
Stir mixture #1 together in a bowl, and mixture #2 in another bowl.
Make sure both are mixed well and the powder has dissolved. Pour
mixture #1 into mixture #2. Do not stir. Allow the reaction to happen
for a minute and when it all starts to congeal, then gently knead it
until most of the water is absorbed.
This amazing concoction will provide hours of fun, with little mess so long as you keep it off the carpets. clothes and wood surfaces. Here's a video of my friend Ben and I. We made a batch of flubber yesterday and had alot of fun with it.
