HOW TO MAKE SLIME?

What You Do:

1. In one bowl mix 1/2 cup (4 oz) glue and 1/2 cup water. Add food coloring if you want colored slime.
2. In the other bowl, mix 1 teaspoon borax with 1 cup water until the borax is dissolved.
3. Add the glue mixture to the borax solution, stirring slowly.
4. The slime will begin to form immediately; stir as much as you can, then dig in and knead it with your hands until it gets less sticky. (No one makes slime without getting a little messy!) Don't worry about any leftover water in the bowl; just pour it out.

What Happened:

The glue has an ingredient called polyvinyl acetate, which is a liquid polymer. The borax links the polyvinyl acetate molecules to each other, creating one large, flexible polymer. This kind of slime will get stiffer and more like putty the more you play with it.
Store it in a plastic bag in the fridge, to keep it from growing mold.

Super Slime

This slime is similar to the one above, but creates a less rubbery and more transparent slime. This is the real gooey deal! (This slime is non-toxic, but still keep these chemicals away from unsupervised children and wash your hands after playing with the slime.)

What You Need:

• Polyvinyl alcohol (PVA)
• Borax
• Water
• Graduated cylinder or measuring cups and spoons
• Food coloring (optional)

What You Do:

1. Make a 4% solution of polyvinyl alcohol: Stir 1.5 teaspoons (approx. 4g) of PVA into 1/2 C (approx 100 ml) of water in a large microwave-safe bowl. Cover the bowl and microwave for 1 minute, then stir. Microwave another 30 seconds and stir. Continue until all the PVA is dissolved. A slight film may have formed on top; you can remove that with a spoon. You can add food coloring if you want colored slime. Allow the solution to cool.
2. Make a 4% borax solution by stirring a little less than 2 teaspoons (approx. 4g) of Borax into 1/2 cup of water.
3. Pour the cooled PVA solution into a ziplock bag and add 2 teaspoons (10ml) of the borax solution.
4. Zip the bag and knead it until the chemicals are mixed into slime. Then scoop it out and play with it.
