How to Make Puffy Slime

Love to play with stretchy, taffy-like substances? Or are you inside on a rainy day with a hankering for getting your hands messy? Here's a recipe for making puffy, fluffy slime for you and your kids.

What you'll need:

• Polyvinyl acetate glue (school glue or craft glue)
• Contact lens solution with boric acid
• Shaving cream
• Food coloring
• Mixing bowl
• Large spoon
• *Vinegar (*Optional ingredient that can be used for cleanup.)

Let's make some puffy slime

Step 1: Add glue

Add about 1 cup (8 ounces) of glue to your mixing bowl.

Step 2: Add shaving cream

Add shaving cream. Here, there's no set amount — the more you add, the puffier your slime will be.

Step 3: Mix

Mix up the glue and shaving cream.

Step 4: Add food coloring

Add in your food coloring and mix. Here, we added 8 drops of blue food coloring and 2 drops of yellow food coloring for an eye-catching teal.

Step 5: Add contact lens solution

Add in your contact lens solution, a little bit at a time. The mixture will start to "transform" into slime rather quickly.

Step 6: Mix some more

Keep mixing your slime and adding contact lens solution until you get the consistency you like. Feel free to use your hands!

Step 7: Voila — puffy slime!

If things get messy, vinegar can help with cleanup.
