If you’re looking for a Halloween slime recipe that’s extra spooky — and a little magical! — this spider web slime is the one to try. At first it feels like a dense dough, but once you start stretching it, it transforms into soft, cottony strands. They look just like a real spider web!
This slime is super soft to the touch and has an amazing cotton-candy texture when pulled apart. It’s such a fun sensory activity for kids, and the stretchy web effect makes it perfect for Halloween parties, classroom activities, or just a cool afternoon craft.

How to Make Spider Web Slime
Materials:
Equipment:
Instructions:
Step 1: Find what you need
- Gather your supplies and materials.
Step 2: Make the borax activator
- Add 1 teaspoon of borax into 1 cup of hot water.
- Stir until dissolved and set in the fridge to cool. Then transfer it into an airtight bottle or jar.
Step 3: Mix the ingredients
- Add 1/4 cup of white glue to a bowl.
- Pour in 1/2 cup of water and whisk the 2 ingredients together gently, until nicely combined.
- Add 1 Tablespoon plus 1 teaspoon of instant snow powder to the bowl.
- Stir the snow into the mixture. The water will absorb the snow, making it a bit thick and clumpy — that’s okay.
Step 4: Activate the slime
- Add 2 Tablespoons of the borax activator into the bowl.
- Stir and press the activator into the mixture, as much as you can.
- Then use your hands to mix the slime.
- Pick up the slime and squish it together. It’ll feel dough-like and overactivated at first, but just keep kneading.
Step 5: Allow the slime to sit
- You can use your slime now, but if you place it in an airtight container for a few hours (or overnight) it’ll give the snow even more time to absorb into the slime.
- Your spider web slime is complete! Stretch it apart to see cotton-y spider web like strands and have fun playing with plastic spiders!
Helpful Tips:
- Don’t worry if it feels “wrong” at first: Right after mixing, the slime may feel over-activated, grainy from the instant snow, and tough to stretch without breaking. This is totally normal! Just keep kneading (really knead, knead, knead) and the snow will eventually soak in.
- Give it time: You can use your spiderweb slime right away, but if you let it sit for a few hours (or overnight), the slime will soften up and become super stretchy with that cotton-like, webby texture.
- Try a colour twist: If you add food colouring to the water and glue before mixing in the instant snow, you’ll end up with a bright and fluffy cloud slime variation.
- Store it properly: Keep your spider web slime in an airtight container when not in use. This helps prevent it from drying out and keeps the texture soft and stretchy for days of play.
What glue is best for making spider web slime?
White school glue is the best choice for this recipe. It gives the slime its bright white colour so it looks like a real web, and it combines perfectly with the instant snow to create those wispy, cotton-like strands.
What is instant snow?
Instant snow is a super-absorbent polymer that expands up to 100 times its size. When water is added the powder grows and looks like real snow! It’s commonly used for sensory play, winter displays, and, of course, for making fun textures in slime.
Where can I get toy spiders to play with my spider web slime?
You can find small plastic spiders online or at the dollar store, especially around Halloween.
If you want a DIY option, try making one from pipe cleaners and a pom pom (check our paper spiderwebs post for instructions!), or baking a mini spider from black polymer clay.
This spider web slime is the perfect mix of spooky and cool, with its fluffy strands and its super soft, stretchy feel. Whether you’re making it as a Halloween party activity, a sensory play idea for kids, or just a fun afternoon craft, it’s sure to impress.
There’s something sooo satisfying about stretching this dough-like slime out into long, wispy webs and then placing toy spiders on it for an extra play element. It’s oozy, stretchy, and a little creepy, making it the ultimate hands-on Halloween fun!
