Base slime plus 5 fun variations.

Slime is endlessly satisfying to make and play with because of its unique non-Newtonian texture that flows like a liquid but holds its shape like a solid. The magic happens when polyvinyl alcohol in school glue cross-links with the borate ions in the activator, creating long, flexible polymer chains. The result is a smooth, stretchy, squishy material that is tactilely irresistible. You can customize it endlessly with color, glitter, foam beads, or scent. It stores well in an airtight container and is a great hands-on project for kids and adults alike.

Ingredients

Basic borax method

• 1/2 cup white school glue (like Elmer’s)
• 1/2 cup water
• 1/2 teaspoon borax powder
• 5 tablespoons warm water (for borax solution)
• Food coloring (optional)
• Glitter (optional)

Directions

1. In a bowl, mix the glue and 1/2 cup water together until fully combined.
2. Add food coloring or glitter to the glue mixture if desired and stir well.
3. In a separate small cup, dissolve the borax powder in the 5 tablespoons of warm water. Stir until fully dissolved.
4. Slowly pour the borax solution into the glue mixture a little at a time, stirring constantly.
5. As you stir, the slime will begin to form and pull away from the sides of the bowl.
6. Once it comes together, knead it with your hands for 2 to 3 minutes until smooth and stretchy.
7. If it is too sticky, add a few more drops of borax solution. If it is too stiff, add a tiny bit of water.
8. Store in an airtight container or zip-lock bag when not in use.

Variations

• Fluffy Slime: Replace half the glue with white shaving cream for a light, airy texture
• Glitter Slime: Add 2 tablespoons of fine glitter in step 2
• Glow in the Dark: Use glow-in-the-dark paint instead of food coloring
• Scented Slime: Add a few drops of essential oil or extract (vanilla, peppermint) in step 2
• Contact Solution Method (Borax-Free): Use 1/2 cup glue, 1/2 teaspoon baking soda, and 1 tablespoon contact lens solution as the activator instead

Tips

• Use clear glue instead of white for a transparent or jewel-toned slime
• Warm hands help activate and smooth the slime faster
• If slime gets stringy or breaks apart, it needs more kneading
• Keep away from fabric, carpet, and hair as it can be difficult to remove
• Slime keeps for 1 to 2 weeks in a sealed container at room temperature
