Is it a liquid or a solid? It's both -- it's gloop.

If Sir Isaac Newton, the British scientist who gave us the theory of gravity, were alive today, he just might be confused by gloop. Gloop, a solution that behaves a little like a solid and a little like a liquid, seems to defy the laws of gravity.

When gloop is molded into a ball, it stays that way for a short time, but then gravity pulls it down -- and it becomes a liquid. Amazing!

What You'll Need:

  • Borax
  • Teaspoon
  • Glass
  • Measuring cup
  • Water
  • Mixing spoon
  • White glue
  • Bowl

Step 1: Mix 1 teaspoon borax with 1/3 cup warm water in a glass. Stir well.

Step 2: Mix 1/6 cup white glue with 1/6 cup water in a bowl. Stir well.

Step 3: Mix 3 to 4 teaspoons borax solution into the glue. Using less borax makes a slightly stickier gloop. When the gloop gets thick, knead it with your hands.

Step 4:. Play with the gloop, and discover its properties. Notice how far it can be stretched. Mold it into a ball. Put the ball in the center of your palm. Observe how the ball becomes a liquid and drips between your fingers.

Safety reminder: When you're finished experimenting with your gloop, place it in a plastic bag and toss it in the trash. Don't pour it down a sink; it will clog pipes. And as with other chemistry activities, don't eat anything you make.
