How this list was compiled: Our own list, written for this page on 9 October 2026: no list, video or site was copied, and each line says in our words what the add-in does. Checked that day against the glossary of slime textures at https://www.wikihow.com/Types-of-Slime and the English Wikipedia article on homemade slime, https://en.wikipedia.org/wiki/Slime_(homemade_toy) : soft clay for butter slime, instant snow for cloud slime, shaving foam for a light and airy slime, foam, bingsu and slushie beads, sponge cubes, plastic snow, extra water, sand and gravel, and lotion, shampoo, soap, sequins, glitter and glow as things slime is made with. The list is for slime that is already made, so it has no recipe and no activator. Licence: own work

How it works

Got slime and nothing new to do with it? Mix in something from the craft box or the bathroom cupboard, from foam beads to googly eyes.

Read the full guide

Try it on a small piece first

Pull off a small lump and mix the add-in into that. Play sand, fine glitter and acrylic paint never come back out, so the rest stays plain if you hate the result. Buttons, pony beads and toys can be picked out, rinsed and used again.

Ask before you borrow body lotion, fruity shampoo or old eyeshadow.
Mix on a tray. Food coloring and acrylic paint can stain a table.
Beads, gems and charms are small parts. Keep the slime away from babies, toddlers and pets.

Questions and answers

What are some random things to add to slime?

Try one of each kind: foam beads for crunch, soft clay for butter slime, chunky glitter for sparkle, a scented marker for color and smell, and a toy ring to hide.

What household items can you put in slime?

Plenty: buttons, cut-up plastic straws, foil balls, pencil shavings, sponge cubes, toothpaste, body lotion and shaving foam. Dryer lint works too, if you want a gray, fuzzy slime.

What can I put in slime to make it crunchy?

Beads. Foam beads make slime crunchy and noisy, bingsu beads trap air for a sizzly crunch, and slushie beads are hard pellets you can hear. Aquarium gravel, buttons and plastic fake snow work too.

What makes slime fluffy?

Shaving foam. Folded in, it makes slime light and airy. Instant snow, wet first so it puffs up, makes cloud slime: fluffy, and it drizzles when you stretch it.

What should you not put in slime?

This list leaves out food, and also water beads, magnets, glow stick liquid, nail polish, perfume and cleaning products. Hole-punch dots and fresh leaves last one day, then the slime goes in the trash.
