Slime care

How to look after GOOEYY.

Slime is a living texture — it reacts to your hands, the air and the weather. Look after it properly and it stays good for a long time.

Beginner tips

Three things to do every time — before the lid even comes off.

  • Strawberry Matcha Latte slime being scooped back into the jar

    Wash your hands. Clean, dry hands first. Lotion, dust or leftover food makes slime cling and leave a film.

  • Mocha Frost slime jar with chocolate drizzle, coffee beans and a straw

    Mix activator first. Make the cup before you open the jar, so you’re never waiting around with slime on your hands.

  • Matcha Boba slime jar with the lid ready to go on

    Lid on tight. When you’re done, every bit goes back in the jar and the lid clicks shut. That’s how it stays stretchy.

In every box

Activator.

One teaspoon of borax comes with your order. That makes a cup of activator.

  • 1 tsp borax
  • 1 cup warm water
  • ½ tsp at a time

For slime only. Wash hands after. An adult should mix it.

  1. A teaspoon of borax held over a cup of warm water01

    1 tsp + 1 cup. One level teaspoon of borax into exactly one cup of warm water.

  2. Activator being stirred in a glass measuring cup02

    Stir until clear. Mix until the powder is gone. That’s your activator.

  3. A little activator being added to pink slime03

    Add a little. ½ tsp at a time, or a light dip. Fold, wait, then add more only if needed.

While Playing

Keep it moving. Stretch, fold, poke, swirl — slime likes warm hands and a little rhythm. If it starts clinging, don’t panic and don’t drown it. A tiny dip of activator, then fold it back in. Play on a clean tray or mat so glitter, cream and pearls stay in the slime, not on the sofa.

  • 02Temperature

    Warm hands make slime softer and stretchier. Cold rooms make it stiffer. That’s normal — hold it for a minute and it loosens up. Keep jars off radiators, out of cars in the sun, and away from heaters. Heat can melt the texture. If it’s been somewhere chilly, play with it before you reach for activator.

  • 03If It Gets Sticky

    Sticky usually means it needs a whisper of activator, or your hands weren’t clean. Wash, dry, then dip a fingertip of activator — half a teaspoon or less — and fold. Wait ten seconds. Repeat only if it’s still grabbing. Too much activator makes it rubbery and sad. If it melted from heat, let it cool first.
