Best Fluffy Slime Recipe - I'm Hooked!
Creating this fluffy slime recipe has made me wonder...why have I waited so long to make homemade slime? This stuff is amazing!
Fluffy slime is so much fun to make, plus it's a great opportunity for a hands-on, science experiment based playtime!
I've discovered so many different slime recipes and can't wait to try more. To start, I chose to learn how to make slime with glue, shaving cream, saline solution and an optional use of borax.
I’m finding that you can play around with these recipes a little bit as you learn more about them. I have a lot of things I would like to try and to learn in the future! This is my first venture, so I'm :-).

Safety Precaution!
This is the perfect kid's craft for older kids. You should handle the ingredients and the final product safely and with caution. They are not edible!
Keep that in mind and please thoroughly read my science explanation and safety tips below before making this recipe.

Fluffy Slime Ingredients and Supplies
You don't need many ingredients or materials to make this fun fluffy slime recipe! Gather the following slime ingredients, and keep in mind they are not suitable for young ages:
- PVA glue- white school glue is better than clear glue for this recipe (like Elmer's School glue)
- Water
- Baking soda
- Shaving cream- spray foam type in a can
- Saline solution- a brand of contact lens solution that includes boric acid and sodium borate- read the ingredient list! Find in the store section for “eye products”, it's a solution used for contacts.
- Borax- found in the laundry section (optional- but I used it in this video)
- Optional Extra Ingredients: Food coloring, Glitter
- Equipment: Mixing bowls, Measuring cups and spoons, Silicone spatula (for stirring)

How to Make Fluffy Slime
Once you have your ingredients and equipment gathered, it's time to mix up a batch of slime!
Stir the mixture with a silicone spatula until the Borax mixture has been fully mixed in (the very last step) and the slime is pulling away from the bowl.
Make the first Borax mixture
Important: Keep this mixture away from younger children and pets. Throw away all extra solution when you finish.
I started by making a borax solution. To a medium sized mixing bowl measure out and add a cup of warm water and 1 tablespoon of Borax.
Borax powder is a product used when washing clothes to help make the laundry detergent work better. I keep it on hand because we live on the farm, and we have hard water. Borax helps make dirty clothes clean again!
Stir this mixture until dissolved and then set aside.

Make the second glue mixture
Now pull out a large mixing bowl for the glue mixture. In this bowl, add ½ cup of warm water and 1 whole cup of glue.
Now if you’d like to, you can purchase glitter glue to add into your recipe (I bought mine at the Dollar Store). But plain white glue or Elmer's glue will work and you have the option of adding glitter in a bit.

Add shaving cream
Mix the glue and the water together a bit, then add 3 to 4 cups of shaving cream. This was fun, spraying the foam made the best hissing noise!
I measured out the shaving cream, but if you would prefer, you can just squirt a large amount into the bowl!
Add baking soda
To this mixture, add a half teaspoon of baking soda.
Now I just want to reminder you to note the difference between baking soda and baking powder! We need baking soda in this recipe, NOT powder.

Choose food coloring and glitter
Next, I added a few drops of food coloring (optional) to my mixture (mine was a gel but liquid food coloring works too).
Some of my glue was a glitter glue, which already had a little bit of blue coloring in it. However I wanted it to be a bit more vibrant so I added more blue food coloring!
At this point, you could add other things to your solution as well. I would’ve added glitter to it if I had it. I have it somewhere in my “stash” but just couldn’t find it. 🙁
Add saline solution
After you've mixed these ingredients, add 2 Tablespoons of saline solution. Saline solution is a slime activator (it activates a chemical reaction)!
As I said in the supplies list, your saline solution needs to include boric acid and sodium borate. Read the label on the saline solution container before purchasing, to make sure it has these ingredients.

Slime, Craft, AND Science Experiment!
The perfect fluffy slime recipe just happens to be a craft AND a science experiment - SCORE!
This is where the magic begins to happen.
As you mix, you’ll see a chemical reaction begin take place. Pretty cool - this is just the best way to mix science with crafts!
The glue is a PVA glue (polyvinyl acetate) with molecules that are in a liquid form. The saline solution contain boric acid and also is in a liquid form (the borax solution too).
When we combine the activator boric acid (molecules in the saline solution and later in the Borax) and polyvinyl acetate (in the cup of Elmer glue), we trigger a chemical reaction. Specifically, the borate ions in the boric acid trigger a chemical reaction in the polyvinyl acetate!
Whew, I'm a home ec teacher, not a science teacher, but this is fascinating.
The molecules in this new solution become long and stringy. As a result, the mixture changes and becomes something between a liquid and a solid. This is a non-Newtonian fluid.
The mixture has new properties - new ways of acting and feeling. It moves through your fingers and oozes into the shape of whatever container you put it in. In other words, it's slime!

Finishing Your Fluffy Slime
In this final step, the ingredients interact and begin to thicken and pull away from the sides of the bowl as you stir. (And now you know why!)
As you mix, you may find that you don’t need to add anything more to the mixture. Your slime may just start setting up and that’s all you need to do.
However, if your slime is too sticky and you'd like it to firm up, you can use the Borax mixture. I do make that ingredient optional, because you may not need it.
I wanted my slime to firm up a bit more, so I used a little of the Borax solution. Add one tablespoon of the Borax solution to the glue mixture in the large bowl. Mix thoroughly and it will begin to set up even more.
When your mixture pulls away from the bowl, you are ready to start playing with the slime!

A Science Experiment You Can Play With!
Once you finish the fluffy slime, the science experiment is ready for sensory play! I couldn’t wait to get my hands into it, the texture was so neat.
So I played around with it for a while and began to knead it. And as I kneaded the slime it firmed up more and more, so it was less sticky and easy to handle.
Mine probably got even a little bit too stiff by the end, I would have liked stretchier slime. But it had such a fluffy consistency and I had so much fun playing with it and pulling on it.
This recipe is large enough for several kids to play with. Simply divide the final slime into portions for each child to handle easily. They could make theirs different colors and add in more glitter into their own homemade fluffy slime. It could be a contest to make the best slimes!!
How to Store Your Slime
Your slime will last a number of days if you keep it in an airtight container.
This "How to Make the Best Fluffy Slime Recipe for Kids" was my first attempt at slime but I promise you it won’t be my last! I'm hopping on the slime craze.

Variations on Slime Recipes
Now that I've made my first DIY slime recipe, there are more I’d like to try. I plan on making all kinds of slime forms- like regular slime with a basic recipe, clear slime, glitter slime, unicorn slime, cloud slime. I've discovered there is way more to life than just fluffy shaving cream slime 😉
In the future, I'd like to make a slime that would be better for young children, with more simple ingredients. Perhaps a more basic slime recipe like a liquid starch slime- one that isn't a borax slime with shaving cream.
Play with add-ins, like adding in some small beads for example. Maybe putting sand in it or some other substance that would give it a feeling of texture that’s different yet.
This is my first time making this I’m late to the party, but I thought it was so much fun!

Safety Precautions- Important!
- Use this recipe with older children!
- Keep young kids and pets away from borax. Be sure to throw all extra borax solution away when done.
- Shaving foam can burn your eyes so don't touch or rub your eyes while handling.
- Stir the mixture with a silicone spatula until the Borax mixture has been fully mixed in and the slime is pulling away from the bowl.
- Wear gloves if you have sensitive skin. I had no problems, but others may. Also food coloring can put color on your skin.
- Work over a table or flat surface as I'm guessing that slime would stick in carpet.

Craft Tips
- White Glue- Use Elmer's white glue or other brand of white glue to make the fluffiest slime (PVA glue- white glue is better)
- Halve or Divide- This recipe is large, so if you are making for one child I would suggest cutting it in half! If multiple children are playing with the slime, simply divide in portions for each.
- Too Sticky?- If your slime is a bit sticky, add a little saline solution or baby oil to your hands before picking it up

I noticed this reading the recipe, and have been wondering if that meant the shaving cream was an optional ingredient that was forgotten.
It is confusing.
