About: I work at instructables by day, and turn into a stitch witch by night. follow me on instagram @jessyratfink to see what i'm working on! ^_^

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

Ingredients:

Double check that the saline contact solution you're using has boric acid as an ingredient, otherwise the recipe will not work.

Tools:

  • 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

    As a teacher of over 35 years I have made this slime stuff before it was ever on anyones radar. I use white or clear school glue and liquid starch and that is all. ( maybe some food coloring)

    Nope! I haven't had any color transfer on hands, surfaces or storage containers. It holds glitter in well, too. :)

    I think the main problem with Borax powder is getting it to dissolve. Besides, the contact solution is already liquid and comes in contact with peoples eyes and so should be safe to use with your hands especially in such a tiny amount.

    I made this with a grand and it sure didn't look like yours. Don't the amount of ingredients u used but only had a half cup finished product. I must have kneaded it for 7-8 mins and she did more. Finally it set up and I ended up with abt 1/2 cup of slime. Don't know if it was worth all that. Tks sue

    My 6 year old enjoyed making it. I guess one generation's "Silly Putty" is another generation's "Slime"! Thanks for the tips.

    So, instead of using sodium borate, you are making sodium borate in the plastic container?

    You can also use liquid laundry starch to avoid any contact with borax or boric acid

    You know how slime works right? So laundry detergent DOES in fact have borate or something like that in it for it to work.

    All such recipes I've seen online DO feature borax among the laundry starch's ingredients.

    Great recipe, but just to point out, "boric acid" IS borax. so this isn't actually "without borax." Probably harmless anyway.

    Can you perhaps explain the worry about slime made with borax? I was always under the impression that, once the polymerization process has happened, the (very weak) borax solution does not pose any threat to the user. I have had many tens of thousand of kids over the past 15 years make slime during workshops without a single incident of sensitivity to the slime. Also, borax is not listed as a possible carcinogen etc.
