Butter slime doesn’t actually have butter in it. But it has a cool buttery-like texture instead which is probably where it got its name from. It’s also not as stretchy as you would expect, but more moldable and fluffy. Most butter slime recipes you’ll find have some sort of soft clay added in. We have used Model Magic clay since it’s non-toxic. You can also try a different form of soft clay but be sure to check that it’s non-toxic also.

How to Make Butter Slime

Butter Slime

We tested many different recipes for butter slime and found most of them to be not that stretchy.  We actually tested about 10 different recipe variations before we were finally happy with this butter slime recipe.

From all the recipes we tested, butter slime is not very stretchy. We’ve added in water, baby oil and baby lotion to help make it stretchier. If you do not want it to be stretchy and want it to be more of a moldable substance you can skip these ingredients. The reason it’s not that stretchy is from the Model Magic – so adding lotion and oil help to make the Model Magic stretchier and more pliable.

The butter slime will be the most stretchiest when you first make it. If it sits out too long the clay will start making it harder, so when it’s not in use we recommend sealing in an air tight container to preserve it.

This slime is really easy to make and leaves very little mess on your hands since you don’t have to use any food coloring. We like to use colored Model Magic for this reason. You won’t end up with any stained hands from having to color your glue with food coloring.

The Model Magic is also fun to play with and if you have extra you can use it to turn it into something else! If you keep the Model Magic sealed after use you can continue to use it like playdough and sculpt and make different things.

What is Slime?

Slime is a polymer because it has qualities of both a solid and a liquid. Other examples of polymers are Jell-O, gum and rubber bands. Glue is also an example of a polymer. A polymer is made of long chains of polyvinyl acetate molecules. These chains slide easily between one another making the substance pourable.

The Science Behind Slime

Making slime is fun for kids but it’s also really cool science! Explain the science to your kids when you mix the contact lens solution with the glue. When you add boric acid (contact lens solution) to your glue, it counteracts the glue and forms a viscous substance. This turns into slime and can be shaped and stretched. The slime forms when the glue molecules cross-link with the borate ions in the contact lens solution. This is a bond that causes the large molecules to no longer slide freely past one another (like the substance was when it was a glue). Therefore resulting in slime!

Will This Butter Slime Recipe Work? 

If your slime has failed and does not turn into slime it’s usually due to not having one of the correct ingredients. In order to make sure that your slime turns out –  please be sure to read the instructions and ingredients carefully.

Contact Lens Solution:  The type of contact lens solution and glue you use is very important. Substituting these ingredients for other brands may result in your slime not working.

Glue: We prefer Elmer’s regular white glue for most of our slime recipes because it is quality PVA glue. Dollar store glue or other brands of glue may not work as well. We also like to stay away from Elmer’s Glue All or natural brands.

Safety tips: Adults only should make the slime and handle all chemicals. Do not substitute any ingredients in our slime recipes. If you have sensitive skin, wear gloves while playing with the slime. Always wash hands before and after use. If you notice any skin irritation discontinue use immediately. See the bottom of the post for more safety precautions. 

How Long Does Butter Slime Last?

Keep your butter slime stored in an air tight container or bag and it will last at least 1 week. We like to store in a Ziploc bag so we can press out all of the air from the bag.

Ingredients Needed to Make Butter Slime

– Elmer’s White Glue (8 oz) –  Note: We have only tested this with Elmer’s glue and recommend this brand as other brands may not work.

– 1 TSP baby oil

– 2 TBSP baby lotion

– 1 TSP Baking Soda

– 3 TBSP water

– 1 TBSP of Contact lens solution. **Important: your brand of contact lens solution must contain boric acid and sodium borate. We like this brand the best and use it in all of our slime recipes. See our full contact solution slime recipe for the brands we recommend.

How to Make Butter Slime

1. Pour 8 ounces of your white glue in a bowl.

Tip: We like to buy the large gallon-size of Elmer’s Glue since it’s the most economical. It’s easy to pour and measure out your glue with measuring cups and you can use it to make lots of batches of slime!

2. Mix your baking soda in.

3. Add you water and mix thoroughly.

4. Add the baby oil and lotion and mix.

5. Add 1 tablespoon of contact lens solution and mix.

6. Pour the slime out on the table as it will be very sticky still. This is what you want since when you add your clay it will take the stickiness away.

Add a little amount of clay (as pictured below) and fold over your slime and knead it into the slime. Keep kneading until your slime is colored and the clay is thoroughly mixed.

7. The more you knead the less sticky it should be until it feels like regular slime. You can now stretch and fold a few times and create your own swirl!

Clay Butter Slime

We hope you love this butter slime recipe as much as we do! You can also substitute the clay and add some cornstarch in for a similar consistency. We would recommend about 2-4 tablespoons of cornstarch.

Butter Slime Recipe with Model Magic

6 comments on “Butter Slime”

  1. Our slime came together well and very suddenly turned into a clumpy porous mess, dripping coloured liquid everywhere. It was though the solid and liquid were splitting apart. Any ideas what might have gone wrong? We’ve tried a version with cornstarch as well, which turned just as awful.

    • Magda did you use Elmers glue and Renu or Equate contact solution? It could be any one of the ingredients that could be the problem. We recommend you try with the same ones we used and if it’s still an issue you can skip the water but the slime won’t turn out as stretchy.

  2. I put too much baking soda now it’s runny. What can I add to make it form

  3. What is the purpose of the baby oil and lotion? Can it be left out?

    • The model magic makes the slime hard so if you want it to be stretchier the lotion and the oil help soften it up and make it stretchy. Otherwise if you want a more moldable, playdough like substance then you can leave it out. 🙂
