Short answer: slime becomes less sticky mainly by adjusting its water/adhesion balance and activating or absorbing excess glueiness with compatible additives. Common methods include kneading, adding small amounts of activator or absorbers, and giving the slime time to breathe. Here’s a practical guide you can follow.

Quick fixes

• Knead more: Spend a bit more time folding and stretching the slime. It helps the slime bind to itself rather than your fingers, reducing stickiness.
• Add a tiny amount of activator or binder: If your slime uses contact solution or a similar activator, try adding 1/8 to 1/4 teaspoon at a time and knead until incorporated. This can decrease tackiness without making it too stiff.
• Introduce a tiny amount of baby oil or lotion: Start with 1/4 teaspoon, knead well, and adjust up or down. Oils coat the slime surface, reducing stickiness.
• Let it “breathe”: Place the slime in an open container for 15 minutes to an hour. Air exposure can reduce surface tackiness, especially for clear/slime that feels sticky on contact.
• Add a pinch of baking soda (for glue-based slimes): Mix in 1/8 teaspoon at a time and knead. This can help neutralize excess adhesive properties.

If sticky persists

• Check glue type: Clear glue-based slimes can be more prone to stickiness; switching to or adding a small amount of a compatible activator can help balance.
• Use a different adhesive balance: If the recipe is too glue-heavy, replacing a portion with a non-glue component (like adding a bit of shaving cream or foam beads) can alter the texture and reduce tack.
• Avoid over-hydration: Adding too much water or saline solution can make slime runnier and stickier; introduce thickening components gradually.

Safe, common additives

• Contact lens solution (as an activator) in small amounts, kneaded in thoroughly.
• Baby oil or mineral oil for surface lubrication.
• Baking soda as a binder to cut stickiness.

If you’d like, share the exact slime recipe (glue type, activator, any add- ins) and current texture (sticky, runny, or stretchy but tacky). With that, more precise step-by-step adjustments can be recommended.
