I've been playing with slime recipes recently, and I have to say this is my favorite one so far! This slime is fool-proof - I've never had a batch fail on me. It's stretchy and squishy and all the things that slime should be. :D
Also, this slime is borax-free! (Great for those who are worried about using borax in something that will be touched so much with bare skin.) It's also made with two common things found in many homes: baking soda and saline contact solution!
The base of this slime recipe is Elmer's clear school glue, which is easy to find online if your local stores are out of it. (I know mine have been!)
Step 1: Tools + Ingredients
- 5 oz bottle Elmer's clear school glue
- 1 tablespoon baking soda
- 2 teaspoons saline contact solution (needs to contain boric acid)
- Food coloring as needed
Double check that the saline contact solution you're using has boric acid as an ingredient, otherwise the recipe will not work.
- Bowl for mixing
- Measuring spoons
- Spoon for mixing
- Small air-tight container for storing (optional)
Step 2: Combine the Glue and Baking Soda
In a small bowl, stir together the glue and the baking soda. Make sure the baking soda is entirely incorporated - there should be no dry bits left. The mix will look fairly cloudy.
Step 3: Add Food Coloring
Add a couple drops of food coloring and mix. Add more as needed to reach the color you want!
Step 4: Add the Contact Solution
Add one teaspoon of contact solution and stir well. The mix will start to become really sticky - stringing from the sides of the bowl and getting stuck to the spoon.
Add the second teaspoon slowly, stirring constantly. As soon as the mix starts to pull together and come away from the sides of the bowl, you've added enough!
At this point, you should have a slightly sticky lump of slime. :D
Step 5: Knead for 2-3 Minutes
When you first remove the slime from the bowl, it will be sticky and thin. To remedy this, you've got to knead it!
Work the slime between your hands and on a clean surface - stretching and compressing it. This will help it become less sticky, softer, and also allow it to stretch properly.
Once it's nice and stretchy, you're ready to play with it!
Step 6: Tip: Easy Clean Up
The slime sticks to itself like crazy, so you can use the blob of slime to clean up your bowl and spoon. Press the slime against any bits left and they will come away cleanly. :)
Step 7: Storing the Slime
This slime can be played with multiple times as long as you store it in an air tight container! As it ages, it will lose elasticity, but it's possible to knead it and bring some of it back.
You may find that it releases a bit of liquid as it's stored - knead that back in and you'll have nice stretchy slime again in no time. If the slime snaps when stretched, kneading will help make it softer again too!
Enjoy your slime!
P.S. I'd love to see pictures if you make it! :D
