Thinking slime, therapeutic putty, silly putty, stress putty, or as we like to call it fidget slime! What ever you want to call it, you can now make it yourself! Our DIY putty recipe is super easy and fun to make. It’s all about the slime consistency that makes this type of slime recipe AMAZING! Let us show you how to keep little fingers busy!




We stumbled upon this putty recipe once day when we were conducting some slime experiments. My son was wondering why we add an equal amount of water to glue in all our slime recipes, so we decided to experiment with what happens when you don’t add any water!




You already know that slime is an awesome sensory activity for kids, but did you know it is also a very cool science demonstration? Well it turns out of you don’t add water to glue when making slime, you will actually make yourself a fun homemade thinking putty instead.

Our DIY slime putty recipe is one of our classic slime recipes minus a step. How cool is that? We found some neat containers at the dollar store to store our homemade putty. Now everyone can take it out and squish it. Why not add some thinking putty to your own homemade calm down kit!

If you are used to our other slime recipes, this is a different consistency! Definitely more putty like and firmer but not brittle! We have simple changed the viscosity of this liquid. Have you read up on your slime science yet?

Where as slime oozes and really spreads when left untouched, this homemade thinking putty recipe is much firmer! Perfect for busy fingers!

It doesn’t spread very much when left on a surface. What makes it so PERFECT is how it feels when you squeeze it. Definitely a stress relieving, therapeutic, sensory rich activity!

STEP 5: When it becomes too difficult to continue stirring, remove with your hands and begin kneading. Knead until smooth!

Stir it up! At first your putty will look kind of lumpy and stringy! Don’t think you have failed!

Now it’s time to dig in and start kneading the slime until it’s as smooth as the pictures you see here! It just takes a minute or two to get the right consistency.

Once you have stirred all you can stir. It gets pretty tough to stir quickly! Take it out and knead it as you see below.

Dunk in remaining liquid if you find sticky pockets. Dry your hands and continue to knead as needed {haha}.

You can store your homemade silly putty in any plastic or glass container with a lid. We found these cool little containers at the local dollar store, but we have also seen them at Ikea and Target.

Our little tins have magnets on the back, so our putty sticks to the fridge. Just make sure to wash your hands after you play with it. It is still a science experiment, and borax is not taste safe!

Make a few batches of different colors to keep on hand for everyday use or to give as gifts. Download our free printable labels below!


Also try to keep it off of clothes, furniture, carpets, your hair, and any other soft surfaces. Check out >>> How To Get Slime Out Of Clothes

  2. I am confused. This starts out saying “My son was wondering why you add an equal amount of water to glue in all our slime recipes, so we decided to experiment with what happens when you don’t add water!”

    Then it says “Water {Yes, you do need some!}”

    Finally, the recipe calls for: (STEP 1) 1/4 cup of glue and (STEP 3) 1/4 cup warm water

    Which brings us back to “equal amount of water to glue.”

    Am I missing something?

  4. The activator which is borax still needs to be mixed with water to use. In our traditional slime recipe you would start out by mixing the glue with an additional amount of water separate from what is used to make the borax solution. I hope that clears it up!

  5. Make sure to read through the steps. It is listed as step 3 and tells you how to mix the solution.

  7. Are you able to use tide instead of borax ? This is because I do not have any borax at my home.

  9. Is there any way to make it less like slime and more like actual putty you can buy?

  10. Have you tried this recipe? It is very putty like because it’s different then our original slime recipe.
