Kids love fluffy slime because it’s so fun to squish and stretch but also light and airy as a cloud! Learn how to make fluffy slime with saline solution so quickly you won’t believe it! This is such a simple fluffy slime with glue and shaving foam. I can’t wait to add this fluffy slime to our list of best homemade slime recipes!
WHAT INGREDIENTS DO YOU USE FOR MAKING FLUFFY SLIME?
I get this question all the time! The best fluffy slime starts with the right ingredients and those are
PVA school glue
Foam shaving cream (see more about these ingredients below).
HOW TO MAKE FLUFFY SLIME WITH GLUE AND SHAVING CREAM
Guess what makes the fluff? You got it, shaving foam! Slime plus shaving foam equals fluffy slime! You choose the colors and give it any theme you like. Rainbow, unicorn, galaxy, holiday themes and more!
I use to think making slime was an impossible activity with wasted time and effort and a disappointed kid. Plus, it’s a recipe, and I don’t like to follow recipes! However, our recipes for making slime are really easy to follow. You can get the ingredients on your next shopping trip.
Watch the slime video and see for yourself how easy it is to make slime!
HOW TO MAKE FLUFFY SLIME WITHOUT BORAX
I have also been asked how to make fluffy slime without borax, and technically this fluffy slime recipe does not use borax powder which is often used for the traditional borax slime recipe shown in chemistry demonstrations.
However, this slime uses saline solution. The right saline solution will contain sodium borate and boric acid. These two ingredients are also members of the boron family just as the borax powder is.
We made three batches each in a different color. Although I used the neon food coloring pack, I ended up with very pretty pastel colors due to all of the white shaving cream.
It doesn’t take a whole lot of ingredients to make all of this slime if you can believe it! The slime whips up in just a few minutes!
Fluffy slime is pretty inexpensive to make if you want to do something extra special for your next slime, sensory, or science activity. You can check out how we used dollar store ingredients too!
BEST FLUFFY SLIME FOR KIDS!
We don’t like a sticky slime that really sticks and goops up the hands. Our slimes are a little thicker but still totally stretchy and fun. Make sure to check out our super stretchy slime while you are at it!
The base for this fluffy slime is our famous SALINE SOLUTION SLIME RECIPE with the addition of a special ingredient!
Once we made our first batch of fluffy slime we were hooked and like any good slime making scientist, we wanted to repeat the fluffy slime recipe to double check our measurements.
I like to be able to give solid measurements as opposed to those recipes that say to add until… I need to know the details.
We made two more batches that turned out perfect and made a beautiful bowl of fluffy slime that my son couldn’t wait to get his hands on! I love how they mixed together and made a gorgeous swirl of colors.
Now for the past year, we have been using this same exact fluffy slime recipe with saline solution to make all our themed fluffy slimes!

FLUFFY SLIME SCIENCE!
What’s the science behind the fluffy slime? The borate ions in the slime activators (sodium borate, borax powder, or boric acid) mix with the PVA (polyvinyl acetate) glue and forms this cool stretchy substance. This is called cross-linking!
The glue is a polymer and is made up of long, repeating, and identical strands or molecules. These molecules with flow past one another keeping the glue in a liquid state. Until…
When you add the borate ions to the mixture, it starts to connect these long strands together. They begin to tangle and mix until the substance is less like the liquid you started with and thicker and rubberier like slime!
Picture the difference between wet spaghetti and leftover spaghetti the next day. As the slime forms, the tangled molecule strands are much like the clump of spaghetti!
Where does the fluff come from? The foam shaving cream! Air is pushed into the liquid as it comes out of the can turning it into a solid (but only temporarily. Adding this foam to the slime ingredients creates a fluffy texture. However, once the air leaves the shaving cream, your slime will change consistency too.
Is slime a liquid or solid? We call it a Non-newtonian fluid because it’s a little bit of both!
SLIME FOR NGSS: Did you know that slime aligns with the Next Generation Science Standards? It does and you can use slime making to explore states of matter and its interactions. Check out NGSS 2-PS1-1 for more information!
The volume produced from the shaving cream in the fluffy slime creates such a cool texture, like a cloud. Plus it doesn’t smell too bad either!
Check out the photo story of our saline solution fluffy slime below, and you can see the fun he is having with our new fluffy slime recipe.
Homemade fluffy slime is a truly satisfying sensory experience!
WHIPPING UP YOUR FLUFFY SLIME RECIPE
*SLIME SAFETY: Slime is a chemistry experiment and should be treated with respect. Do not substitute slime ingredients and do not change our recipes. If you have sensitive skin, consider wearing disposable gloves or trying a taste safe recipe instead. Please read more slime safety here…*
I definitely like to call this whipping up slime because of how fluffy it is!
- Measure 3-4 heaping cups of shaving cream into a bowl. You can also experiment with using less shaving cream for different textures!
- Add color! We used neon food coloring, but there are so many choices!
- Next, add a 1/2 cup of glue to the shaving cream and mix.
- Add 1/2 tsp of baking soda and mix.
- Add 1 tablespoon of the saline solution to the mixture and start whipping!
- Once you get the mixture thoroughly whipped and incorporated, you can pull it out with your hands!
TIP: Before removing the slime from the bowl, squirt a few drops of saline solution on your hands. The slime can be sticky to start. It can be kneaded in the bowl as well. Don’t add too much extra saline as the consistency gets less sticky with just good ole kneading. Adding to much saline solution can result in an over activated slime with a rubbery texture.
SUGGESTION: Repeat the fluffy slime recipe with different colors or enjoy the one batch! We made a giant batch of yellow fluffy slime the other day by tripling the recipe!
If you are wondering why your slime has failed, make sure to double check your ingredients and measurements.
BEST WAY TO STORE FLUFFY SLIME!
Sad to say but fluffy slime will not stay amazingly fluffy for a long time! However, even after the fluff has left the slime, it’s still an amazing and thick texture that is still a bit fluffy.
Store this slime in a reusable container and you are good to go for more slime play. I have been squishing, stretching, and swirling my batch of fluffy slime for a few days now!
