Though it's called butter slime, this isn't a recipe, and it doesn't contain any actual butter. This slime gets its name from its smooth, buttery texture and soft consistency. It's perfect for beginners and requires just a few common materials to make.

Materials Needed

Bowl
Contact lens solution
Baby oil (optional)
Laundry detergent
PVA glue
Air-dry clay
Measuring cup
Measuring spoons
Dropper
Mixing stick

An assortment of items are arranged on a light woodgrain table, suggesting preparation for a science experiment or craft activity. The items include: a clear glass bowl, a small glass measuring cup with water, an empty short clear glass, a small blue plastic bottle, a taller white plastic bottle with a nozzle tip, a small clear dish with a yellow substance (possibly playdough or slime), a larger and smaller black measuring spoon, a clear pipette or dropper, and a wooden craft stick.

Step-by-step tutorial

Step 1

Add 1 cup of PVA glue, 1 tablespoon of glycerin, and 2 tablespoons of laundry detergent to the bowl.

A hand holds a black measuring spoon containing a clear liquid over a clear glass bowl filled with a white substance, likely glue. A small amount of the clear liquid has already been added to the bowl, as evidenced by a slightly translucent area in the white substance. The bowl sits on a light woodgrain table. This image appears to depict a step in making slime or another craft project.

Step 2

Mix the ingredients thoroughly using the mixing stick.

Two hands interact with a clear glass bowl containing a white substance, likely glue, on a light woodgrain table. One hand steadies the bowl while the other stirs the mixture with a wooden craft stick. A swirling pattern is visible in the glue, indicating the mixing process. A slight bluish tint within the glue suggests that another liquid has been added. This image likely depicts a step in a craft project, such as making slime.

Step 3

Using the dropper, gradually add 6ml of contact lens solution, adding 1ml at a time while continuously stirring the mixture.

A clear glass bowl containing a thick, white mixture sits on a light woodgrain table. A wooden craft stick rests partially submerged in the mixture, and a hand holds a clear pipette or dropper above the bowl, likely having just added or about to add more liquid. The mixture has a slightly uneven texture, suggesting it is still being combined. This image likely represents a step in a craft or science experiment.

Step 4

Stir until the mixture begins to solidify and take shape.

Two hands are shown interacting with a clear glass bowl containing a thick, white, glue-like substance on a light woodgrain table. One hand holds the bowl steady while the other lifts a wooden craft stick out of the mixture. A thick strand of the white substance stretches from the stick back down to the bowl, demonstrating its viscous nature. This image likely illustrates a stage in making slime or a similar craft project.

Step 5

Knead the slime with your hands until smooth. If the slime feels too sticky, add a bit more contact lens solution.

Two hands hold a mass of white slime above an empty clear glass bowl on a light woodgrain table. The slime is being gathered and folded, showing its pliable texture. The bowl likely recently held the ingredients or the slime itself during its creation. This image suggests the successful completion of a slime-making activity.

Step 6

Next, add the air-dry clay to your slime and mix thoroughly. Your butter slime is now complete.

A clear glass bowl sits on a light woodgrain table. Inside the bowl, a white powdery substance, likely baking soda or a similar ingredient, surrounds a small pool of bright yellow liquid. This image likely depicts the initial stages of mixing ingredients for a recipe or experiment.

Step 7

Try adding air-dry clay in different colours to create colourful butter slime variations. Remember, the slime is not edible, and take care to avoid getting materials on clothing during the making process.

Two hands press down on four parallel lines of pastel-colored slime or playdough on a light wooden surface. The colors are pink, light purple, light green, and yellow. The hands then gather the slime/playdough together and stretch it, revealing the swirling pastel colors inside. The video demonstrates the playful manipulation of a colorful, stretchy substance, likely slime or a similar material.
