Easy 4-ingredient Fluffy Slime

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

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!)

Shaving Cream – 3 cups (750 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!

 

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.
