Sensational Slime

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. What’s an elasto-viscous material? The earth, for one. When the earth moves slowly, as in glacial movement or continental drift, it behaves like a liquid. When it moves quickly or abruptly, as in an earthquake, it behaves like a solid and fractures. Sensational Slime moves and stretches and fractures and slides in the same amazing way. (And parents note: Buying the borax and glue is the hard part. This stuff is simple to make and easily cleaned up with a little water. This slime will also copy newsprint when pressed against the newspaper

Sensational Slime

What you will need:

1 quart plus 1 cup water

1/4 cup Borax (available at supermarkets in the laundry detergent section)

2 large jars with lids

1 cup white glue

Food coloring

Paper cups

Resealable plastic bags

How to do it:

Pour 1 quart of water and the Borax into one of the large jars. Stir to dissolve. Then pour the glue, 1 cup water, and a few drops of food coloring into 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 Sensational Slime, pour 2 tablespoons of the Borax solution into a paper cup. Stir in 6 tablespoons of the glue solution. Watch! The mixture suddenly becomes thick and slimy. Stir hard, then pour off any extra liquid. Knead the slime with your hands until smooth. Place in a resealable plastic bag before gift-wrapping.
