Transcript:How to Make Slime

Hi, I'm Dr. Anne Helmenstine for About.com. I'm going to show you how to make your own polymer slime.

Polymers in Slime

Slime is fun material that you can make yourself using common household ingredients. The ingredients start out as liquids, but when you mix them together chemical bonds form between the molecules in the slime, forming a substance known as a polymer. You encounter polymers every day. Examples of common polymers include the cellulose in paper and trees, keratin in hair and nails, and all types of plastics.

Slime Ingredients

You only need 2 ingredients for slime: non-toxic school glue and borax, which is sold as a laundry booster and household cleaner. If you use clear school glue, you will get transparent slime. If you use white glue, you'll get opaque slime.

Make the Slime

Mix 1 teaspoon of borax in 1 cup of water. Stir to dissolve the borax. In a separate container, mix 1/2 cup of glue (1 bottle) in 1/2 cup of water. You can add food coloring if you like. When you mix the two solutions together, crosslinks will form between the molecules, forming the gelatinous polymer we call slime.

Storing Slime

The slime is non-toxic and can be cleaned from surfaces using soap and water. You can store the slime in a plastic baggie to keep it from drying out.

I hope you have enjoyed this simple polymer slime project. You can get ideas for more projects if you visit me on the web at About.com. Thanks for watching!
