Measure 6 tablespoons and 2 teaspoons of water into a 5-ounce plastic or paper cup. Add two or three drops of food coloring (color is up to you depending on how disgusting you want to get).
Measure 1/8 teaspoon guar (available in health-food stores) and add to water, stirring until dissolved. Wait two minutes or until mixture thickens.
Add 1 teaspoon borax solution (one tablespoon borax in a cup of water) and stir. Borax is available in grocery or hardware stores. The mixture should gel in two minutes - if it doesn't, start over using 1/4 teaspoon of guar.
Store Slime in an airtight container to keep it from drying out. If it gets on material, wet with vinegar to break down gel followed by soapy water.
