Fluffy Snow Slime
❄️ DIY Snow Slime (Easy Winter Activity for Kids & Teens)
Updated for 2025 — clearer steps, better storage tips, and links to the exact ingredients we used.
This winter we had a string of cold, gray days, the kind where going outside just feels like too much. The kids asked if we could make Snow Slime (sometimes called Cloud Slime), and even though I wasn’t overly excited at first, I was surprised at how much fun it was.
I’m not a big slime person, but this one was so fun! I was right there playing with it too… and we even turned it into a Valentine’s Day gift, which you’ll see below!
It’s soft, stretchy, snowy-looking, and honestly really calming to squish. Let’s make some.
⭐ What You’ll Need for Snow Slime
Snow Slime only needs three main ingredients, plus warm water and a couple of bowls. It comes together easier than most slimes, and it’s Borax-free, which many parents prefer.
A quick note on Borax: Borax is in many things, and it is NOT toxic, but it can cause eye irritation, itchy skin, and an upset stomach if swallowed. It is best not to have the Borax crystals in any slime that littles will be using.
Ingredients
- School glue (white glue works best)
- Instant Snow
- Saline solution
- Warm water
What’s the best saline solution for slime?
Any multi-purpose contact solution that contains boric acid and sodium borate will work. The slime needs those ingredients to activate.
Tools
- Measuring cups
- Mixing spoons
- 2 bowls
- Airtight containers (for storing)

Here you can see my daughter making it… she had so much fun! Below are written instructions.
🧊 How to Make Snow Slime (Step-by-Step)
Here’s exactly how we made it
- Pour 2 ⅔ cups of glue into a large mixing bowl.
- Measure ⅔ cup of saline/contact solution.
- Add the saline 1 tablespoon at a time, mixing between each tablespoon.
- In a second bowl, add ⅓ cup of Instant Snow.
- Add ⅔ cup of warm water to the Instant Snow and fluff it up.
- Pour the snow mixture into the glue mixture.
- Mix until your slime forms.
- Play! Stretch, fold, pull, and squish.
It really does look like snow, fluffy, soft, and not sticky at all.
Wonder what it looks like, here is a little closer view. It really has a snow appearance and was perfect for a snow day inside!
🧼 Storing Your Slime
For best results, store Snow Slime in an airtight reusable container. Zip bags work, but they get left open easily and feel wasteful. A small plastic reusable container or even a mason jar works beautifully.
Stored properly, this slime usually lasts several weeks if not longer.
💌 Snow Slime for Valentine’s Day
We loved this slime so much that the kids made it again and passed it out as Valentine’s Day gifts at our co-op! The theme happened to be “snow” that year, so it was perfect.
What we used:
- small containers – these are like the ones in the pictures but see the Quick Update below
- “Homemade with love” stickers
I know slime as a gift sounds questionable, but this version isn’t sticky, drippy, or messy. It’s one of the few Valentine gifts kids will actually use after the party.
Quick Update: I have tried to move away from plastics when other options are available. Depending on the child or situation, I might today put these in 4 oz mason jars to give. Obviously, glass has its own issues, but the mason jar can be reused and doesn’t waste plastic.
🌈Make Rainbow Snow Slime
We made ours white so it looked like snow, but you can absolutely add food coloring if you want something more colorful.
Portion out the finished slime into pieces and knead a few drops of color into each piece. Add more colors to build color if necessary, and you might want to wear gloves… though we didn’t and it wasn’t too messy.
We did this for a local festival. My son and daughter and my daughter’s friend made several colors to sell and offered a rainbow pack that included a white one too. She sold a lot more than I thought she would! Not saying you need to sell slime (ha!), but it’s a fun option if your kids like making things.
🐧 Homeschool & Learning Ideas
Snow Slime is amazing for:
- Arctic animal sensory play
- Winter or snow unit studies
- Arctic biome work
- Hands-on science stations
- Quiet table activities during read-alouds
- Fine-motor play for younger siblings
Add penguins, polar bears, or ice cubes for themed play.
🧊 Why This Snow Slime Works So Well
- Instant Snow gives it a fluffy, cloud-like texture
- Warm water activates the polymer for better stretch
- Saline solution gives structure without sticky residue
- No Borax = no graininess or irritation
- Glue ratio makes it soft and smooth rather than rubbery
This recipe has the best stretch-to-fluff ratio of any we’ve tried.
❄️ Final Thoughts
I hope you enjoy making this as much as we did. Snow Slime works for quiet afternoons, snow days, school breaks, and even holiday parties. If you like this idea… it is included in my January chapter of my Family Binder, a free family planner. Check it out for this and other great ideas!
If you try it, I’d love to hear how it went! Tag me on Instagram and Facebook @bemandfam I love seeing your versions.
Stay warm and have fun,
BEM and Fam 🙂
