How to Make Slime
Easy step-by-step guide to making stretchy, fun slime at home
⚡Quick Answer
Mix white glue with food coloring, then slowly add a borax solution or contact lens solution mixed with baking soda until the slime comes together. Knead it for a few minutes until smooth and stretchy, then store in an airtight container to keep it fresh for 1–2 weeks.
Step-by-Step Guide
Gather Your Materials
You need white PVA glue (like Elmer's), an activator — either borax powder dissolved in water, or contact lens solution combined with baking soda — plus food coloring and a mixing bowl. Lay everything out before you start so the process goes smoothly. Having a measuring spoon nearby helps you control how much activator you add.
Mix Glue and Color
Pour ½ cup of white glue into your bowl and add 2–3 drops of food coloring. Stir thoroughly until the color is completely even with no streaks. This is also the best moment to customize — a few drops of fragrance oil or a pinch of glitter can make your slime unique before any activator is added.
Add Activator and Knead
If using borax, first dissolve 1 tsp borax in 1 cup of warm water to create your activator solution. Slowly drizzle the activator into the glue a tablespoon at a time, stirring constantly — the mixture will start to pull away from the bowl sides. Once it clumps together, lift it out and knead with your hands for 2–3 minutes until the texture becomes smooth, glossy, and stretchy.
Store Properly
Place your finished slime in an airtight container or zip-lock bag, squeezing out as much air as possible before sealing. Stored this way it keeps for 1–2 weeks at room temperature without drying out. Label the container with the date so you know when it's time to make a fresh batch.
Frequently Asked Questions
Is borax safe to use in slime?
Borax is safe when used as directed — always dissolve it in water first (the standard ratio is 1 tsp per 1 cup water) and keep it away from eyes and mouth. The diluted solution used in slime contains a very low concentration, but adult supervision is still recommended for children under 5. If skin irritation occurs, wash with soap and water immediately.
Why is my slime too sticky or too stiff?
Sticky slime simply needs a little more activator — add it half a teaspoon at a time and knead thoroughly between additions. Stiff or rubbery slime has had too much activator; try working in a few drops of white glue or a small squeeze of hand lotion to soften it back up. Always make adjustments in tiny increments, as both problems are easy to overcorrect.
Can I make slime without borax?
Yes — the borax-free method works well for younger children or anyone who prefers to avoid it. Mix **1 tbsp of baking soda** thoroughly into the glue first, then add **contact lens saline solution** a little at a time (start with 1 tsp and add more as needed) until the slime forms and pulls cleanly away from the bowl. The texture may be slightly softer than borax slime but it's just as fun to play with.
How can I make my slime fluffier or more stretchy?
For **fluffy slime**, fold in 2–3 cups of white shaving cream into your glue before adding the activator — the foam creates a light, airy texture that's satisfying to squish. For **extra-stretchy slime**, add 1–2 tbsp of clear school glue alongside your white glue, which increases elasticity without changing the color. You can also knead in a small amount of hand lotion after the slime is formed to boost its stretch.
