So chances are really good if you have a kid (or grandkid…or kid in your life…) between the ages of 4 and 18, your life has been affected in some way by the slime craze. Slime is an epidemic sweeping the nation, causing parents to acquire obscene quantities of Elmer’s glue and congregate, mumbling incoherently, in the laundry detergent aisle as they hunt down that last box of borax at Target at 10:00 pm. If your children have yet to be affected, just wait. It’s coming. And if you’re reading this post, fluffy slime is coming your way ASAP.
making slime
The good news is that it’s easy and it’s fun. If you’ve never made our “classic” slime, check out the post here and. This particular slime is incredibly satisfying to make and to play with–this makes a big batch, but you’re going to need it all, I promise.
You’re going to need some glue (good luck finding any–just buy it online for the sake of your sanity), shaving cream (I like the sensitive skin variety because it doesn’t smell like an adolescent boy who’s discovered Axe body spray after gym class), saline solution (make sure it has boric acid in the ingredients–most in the United States do), water, and borax.
To make the borax solution, dissolve 3/4 teaspoon of borax powder in 1/4 cup of hot water (you’ll need to stir it pretty vigorously to get it to dissolve.)
Add 2 tablespoons of saline solution and set aside.
In a large mixing bowl, combine the glue and 1 cup water. If you’d like to add any food coloring, this is the best time.
It’s also a great time to add in any mix-ins like extra-fine glitter, mica powder or foam balls for “crunchy” slime, 
but you may want to wait and let kids add in whatever they want after the slime is mixed; it’s just harder to incorporate.
(A good rule of thumb–use more of everything than you’ll think you’ll need. More food coloring. More glitter. More more more. Slime is an ostentatious activity.) Mix until the glue/water mixture is completely smooth and and colors/mix-ins are evenly distributed.
Measure out 8 cups of shaving cream (gently pat it down to make sure you don’t have any large air pockets).
Add the shaving cream to the glue mixture and gently stir until combined.
Add the borax/saline solution mixture and mix until combined. The boric acid/borax is what gives the slime its cohesive consistency, so you want to make sure everything is mixed evenly. When you first add it, the mixture will seize up, but as it becomes more and more incorporated into the mixture, the slime will take on an amazing, soft, fluffy, marshmallow-y consistency.

adding mix-ins
If you’d like a little more firmness, you can add up to an additional tablespoon of saline solution, but start small and add a little as you go. If you want to add in your mix-ins now, go for it–for this little batch, we’re doing small styrofoam balls to create what the slime-iverse refers to as “crunchy slime.”
If you don’t mix anything in, your slime is done!
Go play with it!
Over time, the fluff will deflate. Store in an airtight container. Fluffy slime that is left alone in an airtight container will take on a really great, smooth, flat slime consistency after about a week.
I like to store our slime in these 16-ounce deli containers (which are perfect for other things like cookie dough, homemade ice cream, frosting, and other tasty treats, especially when you’re giving them away.)
SUPPLIES USED:
White School Glue (Elmer’s is best)
Saline solution (just get store brand saline solution)
Extra Fine Glitter (I got the packets I used in the picture above at the craft section of Walmart or you can get a large selection of it by following the link)
Borax (or you can find it in the laundry aisle of the grocery store)
Mica powder (makes the slime shimmery instead of glittery)
Tiny Styrofoam Balls (for crunchy slime. Just be forewarned, once the bag is opened, Satan has been unleashed and between their apparent weightlessness and their penchant for static electricity, trying to clean them up will hurt your heart. Just get a vacuum and a prescription for anti-anxiety medication.)
