Dr. Ectoplasm’s Radioactive Slime

By:

Materials

• 1 disposable cup
• Slime base (Elmer's or most kinds of white craft glue)
• Food coloring (you pick the color)
• Water
• Slime Activator (one cup water mixed with one tablespoon of Borax Powder - available at most large grocery stores near the laundry detergent
• A plastic spoon (for stirring)
• A tablespoon (for measuring)

What to Do:

1. Add three tablespoons (20 ml) of water to the slime base (glue) in the cup. Stir well.
2. Add a few drops of the food coloring and stir it up until mixed.
3. Now the fun part...Add one tablespoon of Dr. Ectoplasm’s famous slime activator (Borax solution) and stir well. Watch the slime form!
4. After the slime forms let it sit for about 30 seconds and then pull it off the spoon and play with it.  Keep your slime in a tightly closed plastic bag when you are not playing with it, and keep it away from carpet and your little sister's hair.

Now for the SCIENCE part.... The POLYMER you created is unique because it has qualities of both a solid and a liquid. If you pour it into a container, it makes the shape of the container like liquids do. If you pick it up and play with it, the slime becomes like a solid.  Solid molecules are tight together, but liquid molecules spread out and become drops. But polymer molecules chain themselves together so they can be made to stretch and bend. Some examples of polymers are jello, rubber bands, and gum.  Can you think of any others? Keep your slime in a sealed plastic bag and don’t eat it or feed it to your pets!
