How to Make Fluffy Slime




About: I work at instructables by day, and turn into a stitch witch by night. follow me on instagram @jessyratfink to see what i'm working on! ^_^

In this instructable, I'll teach you how to increase the volume of a normal slime recipe with the help of shaving cream! :D

Fluffy slime is easy to make and super fun to play with. (I made two batches for this instructable in less than 20 minutes!) The texture of fluffy slime is great, too - it's softer and feels incredibly light compared to normal slime.

Keep on reading to find out how to make fluffy, crazy stretchy slime!

Step 1: Tools + Ingredients


  • 3 cups shaving cream (try to find something basic and unscented if possible - I did not care for the smell of the shaving cream. :P)
  • 1/2 cup Elmer's Washable School Glue
  • Food coloring as desired
  • 1/2 teaspoon baking soda
  • 1 tablespoon saline contact solution (must contain boric acid)


  • Large bowl for mixing
  • Measuring cups and spoons
  • Spatula for mixing
  • Plastic container for storing slime (optional)

Step 2: Measure Out 3 Cups of Shaving Cream

Shake the can of shaving cream well. Tip it down into the 1 cup measure and try to fill the cup completely with the shaving cream. I normally measure a little over the top of the cup to compensate for any air pockets.

This doesn't have to be exact - just close!

Step 3: Add 1/2 Cup Glue

Pour the glue into a 1/2 cup measure and add it to the shaving cream in the bowl. Mix well, until the mixture looks smooth like frosting.

Step 4: Add Color and 1/2 Teaspoon Baking Soda

Add in your food coloring - I mixed green and teal.

One note of caution: I found that the food coloring transferred to my hands when I used a lot of it in this recipe. It did wash away easily, but be careful to not go over the top with the food coloring to avoid stains. Because the base of this slime is white, expect a more pastel colored slime.

Once the color is in, sprinkle 1/2 teaspoon baking over the top and mix well.

Step 5: Add 1 Tablespoon Contact Solution and Mix

We're almost done!

Now you'll want to add 1 tablespoon of the saline contact solution to the slime mix. The contact solution will cause the slime to coagulate slightly so it becomes more solid!

Use your spatula to mix the slime together fairly fast for a minute or so. Keep mixing until the slime is mostly in one blob and has pulled away from the sides of the bowl. :)

Step 6: Knead the Slime

Now you'll want to work the slime with your hands.

At first, the slime will be fairly wet and sticky. As you stretch and knead the slime, it will become firmer and drier, but still remain soft!

(If your slime seems really wet, let it sit in the bowl for a few minutes and then try kneading it again. Sometimes the chemical reaction seems to take a little longer!)

Step 7: Mixing Colors

For the main photos, I made a second batch of slime and rolled it with the first.

I love doing this! The slime blends together as you play with it, creating swirls of different colors. As it sits, the colors will become much less distinct. My pink and teal slime became fairly purple after a bit!

Step 8: Storing the Slime

This slime can be used multiple times if stored in an airtight container. :)

It will be less "fluffy" every time you use it, but I still like the texture!

Boric acid is not bad it's borax that is bad

the boric acid is what makes it fluffy with out it its just slime

Actually, without boric acid, it will not be slime. The boric acid is part of the ingredients necessary to make the reaction to produce "slime" - so unfortunately, for kids allergic to boric acid, this will not work, but for everyone else, this is a super cool experiment!

I haven't heard of reactions from boric acid - only from coming in contact with powered Borax. And even those are rare - and rarely "toxic." Snopes has a great article with many sources.

Boric acid is used in many applications with direct skin contact and considered safe. It's even more diluted when added to the slime, too, further lowering the risk of reaction.

Do you have any studies showing toxic reactions in children? I'd like to see it as I never found anything in my research before starting these slime recipes. I always like to make sure I know the risks of what I'm doing so I can communicate that to readers. :)

there are recipes for edible fluffy slime that is made from marshmallows. I think I found a couple variations on another website.

Ye, but you need to stir up the shaving gel first so it gets the consistency of shaving cream.

it didn't work. I think the eye contact lens solution didn't have boric acid.

I didn't use Elmer glue but I did use washable school glue. It didn't stick together properly so I put it in a ziplock bag so I could still get the fell of it!
