How to make Polymer slime

29 07 2008

The slime that we made in camp this week with Elmer’s Glue with Borax and water produces a putty-like material. It’s easy to make, fun to play with, and will teach you something about the properties of polymers. Go ahead, give it a try!

Materials: 2 baggies, bottle of food coloring, eye dropper, bottle of glue, water, borax (find it at the grocery store with the laundry detergent)

1. First mix 2 teaspoons of borax and 1/2 cup of water in a bowl. Set aside for later.  

2. Put 1 Tablespoon of glue into a baggie.  

3. Scoop 1 Tablespoon of plain water and add it to the bag.  

4. Puts 2 drops of food coloring into the bag. 

5. Squeeze the bag gently with hands to mix it. 

6. After mixing, get the bowl of borax water, stir it vigorously, tilt it, and scoop a Tablespoon of the borax water from the very bottom and add it to your baggie.  

7. Seal the bag and squeeze for 2 minutes in order to thoroughly mix the liquids. (now is a good time to observe what is happening to the runny glue. What changes are taking place?)

8. When the slime is thoroughly mixed, over a garbage can, turn the bag inside out and scrape the slime together into a ball with your hand. Throw bag away immediately. 

9. Get a fresh baggie to put your glue slime in when done. Wash your hands and try to keep it off your clothes and the carpet or it will stain!


What’s going on here? Glue is a polymer, which means it’s made up of long chains of molecules. Borax causes the glue chains to link together, making a stretchy, gooey slime!

can you use Talcom powder?

I have not tried using Talcum powder in the slime. I did find this recipe online for how to make Baby Powder Putty.
Have fun experimenting and write back letting us know how it went, if you get a chance!

Is this the same stuff you can put in plant pots to water the plants when they get dry? If not, do you know how to make THAT STUFF???? THANK YOU! My grandson and I will have fun with the slime!

Hi Jim,
Polymer slime is not quite the same stuff as they put it pots, but I think these might be:
Have fun and let us know the results of your experimenting.
Thanks for reading!
