Easy 4-ingredient Fluffy Slime

By Rachelle 59 Comments

My kids are crazy for slime. And they’re clearly not alone! A few weeks ago we made a gorgeous batch of 3-ingredient glitter slime, and today we’re sharing how to make fluffy slime. If you’re on the slime train, there’s a good chance you’ve heard of fluffy slime, and it’s so easy to make. The difference between slime and fluffy slime is that fluffy slime feels like marshmallows. It’s bouncy, puffy, and, well, fluffy!

How to Make Fluffy Slime

We’ve been making slime for years (take a look in the book, TinkerLab: A Hands-on Guide for Little Inventors or click here our original recipe!), and even at ages 7 and 9 they are still nuts about this stretchy magical material. What is it about slime? Well, it’s a sensory material at invites children (and adults) to tap into the sense of touch in a pretty amazing way. The texture is playful and stretchy and encourages children to invent, build, sculpt, play, and even relax. My two played with slime for an hour the other day and they didn’t want to stop.

Fluffy slime ingredients _ TinkerLab

Fluffy Slime Ingredients

Shaving Cream – 3 cups (750 ml) (<<this brand works!)

Elmer’s School Glue – 1/2 cup (120 ml) or a 4 ounce bottle. We love this glue. If your kids love making slime, splurge for the gallon!

Baking Soda – 1 teaspoon (5 ml)

Contact Solution with boric acid as an ingredient – 1 tablespoon (15 ml) (<< this brand works!)

Steps for Fluffy Slime

Step 1: Add shaving cream to a bowl. Don’t worry about exact amounts. This recipe is forgiving and a little more or less will be fine.

Step 2: Add Elmer’s School Glue to the Bowl

Step 3: Add baking soda to the bowl.

Step 4: Mix everything together

Step 5: Add 1 tablespoon (15 ml) contact solution to the bowl. Mix it all together!

Make Fluffy Slime

Step 1: Add 3 cups (750 ml) shaving cream to a bowl. Don’t worry about exact amounts. This recipe is forgiving. 4 cups (1000 ml) would be fine, too.

Step 2: Add 1/2 cup (120 ml) Elmer’s School Glue to the Bowl

Step 3: Add 1 teaspoon (5 ml) baking soda to the bowl.

Step 4: Mix everything together

Step 5: Add 1 tablespoon (15 ml) contact solution to the bowl.

Mix it all together! See the next set of photos to see how it comes together in about a minute!

Mixing Fluffy Slime

Once the slime comes together, remove it from the bowl to knead and stretch it with your hands for a few minutes. It will be sticky at first, but it becomes non-sticky and pliable pretty quickly.

Play with your slime!

Slime Safety Tips and Recommendations

  • When playing with slime, if you’re concerned about it getting on your furniture, be sure to cover the table with oil cloth or a non-porous table covering.
  • Always supervise children when making and playing with slime.
  • Slime is not a food – do not allow children to eat slime. Always wash hands after using slime.

          Not sure what we did wrong, but this did NOT work for us! It never firmed up… was a soupy, sticky mess even after many minutes stirring and attempting to knead 🙁

      Wonderful news! I’m happy to hear that the recipe worked for you. As you suggest, we recommend storing in a plastic bag for a few days, sometimes longer. 🙂

    The list of ingredients has glue first so I did that instead of following instructions. Didn’t turn out properly (however they’re still having fun with it). If you could reorganize your list above the instructions that would be helpful for those who don’t read all the way through. Lol

    Ok so I tried making this as a gift for my son and it sucked I followed the recipe exactly and it didn’t form anywhere near slime. I was extremely upset as I was not able to provide a gift for my son. I think that maybe change the recipe idk. But I do know one thing I will not be using anymore of your recipes.

      It worked for me! Mabye you went wrong somewhere…What was wrong with the slime? If it was too sticky/ runny, add more baking soda and contact solution. If it was too hard you added to much baking soda/ contact solution. You could either try making it again, or microwave it for 30 secs or so and then knead it some lotion to soften it up a bit

    My 4 year old loved this! Can you add food coloring? We used a metallic colored glue the first time. Definitely making more.

      We didn’t try it with this recipe, but you should be able to add food coloring or liquid watercolor 🙂 I bet it was gorgeous with metallic glue.

      Rachelle is right. I did as her tutorial did and it worked! however I am not sure if “similar” components will be successful. because I’m not a chemist ^ _ ^ Now my kid is sitting at home- making my products. And the purpose of me coming back here is to thank Rachelle.
      thank you!

    Hi just asking can you do it with other PVA glue rather then Elmer’s?

      April 5, 2021 at 1:14 pm

      Elmer’s contains PVA, so my best guess is it should work.

    Hi, I made this slime and put it in a container. It went hard after like 3 days. Hope I can get some more glue to make this again. What did I do wrong: where it’s stored?? Help

    • Rachelle says

      April 15, 2021 at 12:41 am

      The shaving foam can lose its fluffiness after playing with it, so it won’t stay fluffy for more than a day or so, and at that point it turns into regular slime. We generally store ours in a zip-up baggie or plastic container. Maybe there was air in your container?

    I think so… I’ll try making some more slime when covid is over and storing it in a baggie with no air. Thank u so much!
