This project is one of those exhilarating activities that everybody loves. By making and playing with this weird substance your child is exploring the scientific properties of an elasto-viscous material.
The earth is an example of an elasto-viscous material. When the earth is moved slowly, as in glacial movement or continental drift, the earth behaves like a liquid. When moved quickly or abruptly, as in an earthquake, the earth behaves like a solid and fractures. Silly Slime moves and stretches and fractures and slides in a most amazing way. And parents note: Buying the Borax and Elmer's glue is the hard part. This stuff is simple to make and easily cleaned up with a little water.
What You Will Need:
1/4 cup Borax (Borax is available at your grocer in the laundry detergent section)
2 large jars with lids
1 cup Elmer's glue
1 cup water
The ingredients for this recipe will make more Silly Slime than you might think you need, which is fine. Kids inevitably want to make more to show friends or to give away.
Place 1 quart water and the Borax in one of the large jars. Stir to dissolve. Then pour the glue, the 1 cup water, and a few drops of food coloring together in the other jar, replace the lid, and shake hard. You now have 2 jars of solution: a Borax solution and a glue solution. To make the Silly Slime, pour 2 tablespoons of Borax solution into a paper cup. Stir in 6 tablespoons of glue solution. Watch!! The mixture suddenly becomes thick and slimy. Stir hard, then pour off any extra liquid. Knead the
