Butter slime is named for its buttery spreadability—when you quickly pull or poke it, it retains its shape and spreads out like butter. This slime is the perfect mix of clay and slime! If you're looking for a stretchy slime to keep your hands busy, butter slime is the ideal choice.

Steps
Making butter slime with clay

Prepare the borax solution. Mix 1 teaspoon of borax powder into 1 cup of hot water until the powder is completely dissolved. Set the solution aside for later use.

Pour 110g of glue into a separate bowl.
Add a small amount of hand soap foam. Press the soap dispenser about 8 or 9 times.
- If you want your butter slime to have a pleasant scent, use a fragrant hand soap foam.

Add a bit of lotion. Press the lotion dispenser 2 to 4 times.

Add 1/2 cup (120ml) of shaving cream.
Mix the ingredients until smooth. The mixture will be thick but smooth, resembling marshmallow cream.

Add a small amount of borax solution to the mixture and stir well. Add only 1 teaspoon at a time and mix thoroughly. You should add just enough borax solution to make the slime thick enough to stick together but not so thick that it becomes hard and no longer sticks to the bowl. The mixture should still be sticky.
- You may not need to use all the borax solution—just a few teaspoons will suffice. Adding too much borax will make the slime stiff and difficult to turn into butter slime.
- Once the slime starts to take shape, it will resemble smooth, stretchy slime, but stickier. This is what you want.

Pour cornstarch into a separate bowl. Estimate the amount of slime you have, then add an equal amount of cornstarch to the bowl.
Place the slime into the cornstarch and knead until combined. It will take some time for all the cornstarch to blend into the slime.
- The cornstarch will make the slime more stretchy and sticky or "runny." This is normal.
- Kneading the cornstarch into the slime by hand is easier but can get messy. If you want to keep your hands clean, try using a mixing tool.

Add a bit more borax solution if your slime is too sticky. If the cornstarch makes your slime overly sticky or runny, add 1 teaspoon of borax solution and continue kneading. If the slime remains too sticky, carefully add more borax solution as needed.
- Avoid adding too much borax, as it can make the slime too stiff. You want it soft and stretchy, not hard and brittle.

Take about 2 tablespoons of clay. You can add more if the slime is softer than you'd like.
Add a few drops of food coloring to the clay (optional). If your clay is white, adding a couple of drops of food coloring will give it color and also tint the slime when combined. Since some food coloring can stain your hands, start with two drops and knead them into the clay. If the color isn’t strong enough, you can add more later.
- To make the slime look like butter, add 2 drops of yellow food coloring.
- If your clay is already colored, you can skip this step.
Knead the clay into the slime. Press the clay into the slime and use your hands to mix both until the texture resembles dough. If the clay is colored, you’ll see the color blend into the slime.
Finally, enjoy playing with your butter slime! Store the slime in an airtight container when you’re done.
Making butter slime without borax and clay

Add 1 cup of cornstarch to a bowl.
Pour in 1 cup (240ml) of shampoo and mix thoroughly. The mixture will become slightly soft and mushy.

Add 110g of glue to the paste mixture.

Incorporate 1 tablespoon of lotion into the bowl.
Add a few drops of food coloring (optional). If you want to create colorful butter slime, adding a few drops of food coloring will make it visually appealing; since some food coloring can stain your hands, start with just 2 drops and add more if needed.
- To make the slime resemble butter, add 2 drops of yellow food coloring.
Stir the ingredients until no lumps remain. If food coloring is added, mix until no white streaks are visible.

Gently mix a small amount of laundry detergent into the slime and stir thoroughly. The slime will begin to clump together as you mix. Slowly add more detergent until the slime no longer sticks to the bowl.
- Avoid adding all the detergent at once! Doing so will cause the slime to harden quickly, making it difficult to play with. Start with a small amount and gradually increase if needed.
Knead the slime with your hands. Once the slime has formed, remove it from the bowl and start kneading by hand to reduce its stickiness.
- If the slime is too sticky, return it to the bowl, add a bit of cornstarch, and knead again. The result should be a soft, pliable dough-like consistency.
Finally, enjoy playing with your butter slime! Store the slime in an airtight container when not in use.
Tips
- Alternative ingredients for borax solution include laundry detergent, liquid starch, or a saline solution with baking soda.
- Try adding accessories to your slime, such as glitter, beads, or other decorations.
- Watercolor can be used as a substitute for food coloring, but be cautious as it may stain more easily than food coloring!
- For the clay method, if you want a glossy finish, add about 1 teaspoon of baby oil while kneading, after mixing the slime with cornstarch and adding the borax solution.
Warnings
- Adding too much laundry detergent or borax solution can make the slime too hard to play with, so be careful not to overdo it.
- Exercise caution when using borax, as it is toxic if inhaled or ingested and can cause burns if not mixed thoroughly.
What You'll Need
