This simple homemade unicorn fluffy slime recipe is the best!
My daughter loves crafting and is obsessed with all things slime, especially unicorn fluffy slime! She loves making slime, playing with it, stretching, and popping it. After she got her first iPhone for Christmas, all she did for days was make slime recipe videos.
I was so excited that my daughter’s first how-to video tutorial for this fabulous Rainbow Unicorn Fluffy Slime Recipe went viral as soon as we shared it! I think she did a wonderful job on her video to show you how to make her fluffy slime.
This unicorn slime recipe is super fluffy and so easy to make. Since we shared this slime, thousands of people have made it! This fun unicorn slime is addictive and once you make it, you might not be able to stop playing with it. We love the neon colors!
Homemade Fluffy Slime Recipe
What you’ll love about this recipe is that it blends three pretty pastel colors into a unicorn slime rainbow!
If you use the exact color combination as pictured below, your slime when combined, should turn a darker shade of gray blue.
Using other colors might make your slime turn a yucky brown color. So be sure to follow directions carefully on this unicorn slime recipe.

Information about Borax in Slime
This slime recipe includes white glue, shaving cream and a small amount of borax powder diluted in water. My daughter has very sensitive hands and this slime does not affect her hands at all.
If you are unsure about using borax, please watch this informative video from Stephen Spangler, the king of science projects for kids.
If you prefer not to use borax to activate the slime, use saline solution instead. If you are allergic to borax, shaving cream or glue please do not make.
About Borax From Parents.com:
Experts like Vanessa Stoloff, M.D., a family practitioner at the University of Pennsylvania, say the whole Borax business is actually pretty benign. In fact, the DIY thing is currently going down in her own home courtesy of her 11-year-old twin daughters, who recently made a batch of cookie dough slime that smelled like fresh-baked chocolate chip cookies. “As long as your kids’ slime recipes don’t include tasting it,” she told Parents.com, “topical Borax shouldn’t affect skin—especially at the amount being used.”
Dr. Jason Hack, a toxicologist from Rhode Island Hospital, also has a daughter who’s into making slime. “It’s a great activity,” he told WPRI 12 Eyewitness News. And he echoed Dr. Stoloff’s arguement that the small amount of Borax the kids are using is not absorbed through the skin. “It would take eating a lot of it to actually become toxic,” he explained.
If your child does accidentally ingest any slime that contains Borax, you should contact the American Association of Poison Control at 800-222-1222 immediately.
What Can You Use Instead of Borax in Slime?
If you prefer not to use Borax to activate the slime, try to substitute with saline solution or laundry detergent. If you don’t use Borax, do not use water and you may need to add baking soda to thicken the slime.
How Do You Make Fluffy Slime?
What makes this slime so fluffy is shaving cream. The fluffy sensation won’t last forever, so play with it right after you make it.

Video
Supplies
- ½ cup white glue
- ½ cup foaming shaving cream
- ½ teaspoon borax powder
- 1 cup water
- Blue, pink and yellow neon food coloring
Instructions
- In a large bowl mix glue and shaving cream with a spoon.
- In a separate bowl or cup, mix 1/2 teaspoon of borax in 1 cup of water. Stir until the borax is dissolved. (To speed up this process, place mixture in a glass cup and microwave for 30-60 seconds.)
- Add about a teaspoon of the borax and water mixture into the glue/shaving cream bowl and stir.
- Knead with your hands and if it’s too sticky, add a tiny bit more borax and water mixture.
- Once your fluffy slime recipe is ready. Separate into three pieces.
- Add a drop of blue food coloring to the first piece of slime and knead until the entire piece is blue.
- Repeat with the other two pieces of slime by adding one drop of pink and one drop of yellow to them.
- When all three pieces are colored, add them together.
- Gently knead the fluffy slime until you have a pretty mixture of the rainbow.
- The longer you knead this slime, the more the colors will become one.
Notes
* Do not make if you have skin allergies to cleaning supplies, glue, food dye or shaving cream.

Love this slime so much!
didn’t work and was super sticky and messy
This is so fun!! The kids thought it was a blast to play with and it kept them busy all afternoon!!
It should last a while if you keep it sealed inside of a container when not playing with it.
What happens if the slime runs out of fluffiness? is there any way to get it back?How long will the fluffiness last?And is there a way to revive the slime after it dries out?

cute now it is my wallpaper
this is so cool
Do you have any recipes for WONDER DOUGH by any chance? Its kinda like play doh but its got a smoother texture and is softer without the sandy texture
Good tip! We use room temperature water.
Ours was a total fail using Borax. Tried it again and heated the water and got a TOTALLY different result. It worked
Awesome! So glad you liked it!
This Slime is AMAZING I tried and I loved i brought it into school and I ended up making more for people in my class and selling it!!! GREAT recipe
tuned out okay. not very strechy, and dries up quickly. but thank you!
Thank you for somewhat wasting my time. Slime amount was barley a handfull and Not strechy at all. Used alot of my glue and wasted it. Not happy at all
It did not say one cup do you even know what 1/2 means?
Very pretty slime
Ingredients listed are way off what a disappointment definitely definitely definitely not one cup of water!
Thanks! I hope she loves it!
Shame on you. That language is completely uncalled for.
We use room temperature water for this.
What type of water do you use for the borax mix (hot or cold or warm?)
This looks so fun!! What an easy “recipe” too!! Thanks, Amy!!
OMG AMAZING… U ARE DA BEST!
OMG AMAZING
Well this looks like sooo much fun! On the to-do list for the week – yay!!!
Amy! This looks so much fun! Going to make with Victoria!
This is so cool! I think we are going to have to do this for a May celebration!
I love it!!!!! It’s one of my favorites!!!!!
Made this today. We don’t usually have success making slime, but this turned out perfect! Thanks so much!
I just Finished making this with my kids.
I found we needed quite a bit of the borax/water solution and it took almost an hour to get the right texture. BUT this was my first attempt at slime, so I likely did something wrong. Either way, my kids are IN LOVE!
Thank you for sharing the recipe ?
I love your Rainbow unicorn slime!
you’re the best thanks
This worked well!!
UNICORN SKLIME BLUE WHUIITE PINK
So glad you liked my daughter’s fluffy slime recipe! Thanks!
Thanks for the great recipe
how do you get the quantityof each ingrediant
Like, way more! We ended up just dumping more of everything into the bowl to make a bigger batch and get it to the right consistency.
1 teaspoon of borax works best for me.
I haven’t done anything yet
But can I use liquid detergent?
Hello! We are planning to make this at my daughters birthday party. To save time (we will have about 30 kids making this slime) can I mix the borax and water ahead of time and have it pre-measured our for everyone? Or does it have to be mixed right before you add it to the glue and shaving cream?
i loved this recipe!
AMAZING
Thank you!
Thanks! So glad you love it!
U have to add more borax and water mixture in the slime than the recipes says
The slime is so pretty. I will plY with it every day it’s so pretty.
You might have added too much activator
This happened to me too.
Thanks for the great recipe, I loved it ??Could you please make other types of slime! Thanks for the great recipe. Keep posting!
This recipe did not work for me. Was too sticky and loose, never came together. Any thoughts as to where I went wrong? Thought I followed it to a tee
We made the slime and it came out well. We started adding the food coloring to each. At first it looked like the picture but then the colors started to mix and we got a puke tan color. Any ways to avoid this?
Thank you
My girls really love everything about making slime. This one is a really good one to make. Thanks
Glad you liked it. Thanks!
It’s so lovely and fluffy. I want to make it every single day,! I made it and it was so lovely. If you stretch it and then you squish it up then it should actually sweek!
Soon beautiful recipe.
It’s so lovely and fluffy. I want to make it every single day,!
Maryam. We need half a teaspoon of borax
I think if you add like melted candy to it without the glue, shaving cream and etc.
your saline solution should contain boric acid and sodium borate i use bausch and lomb and it works perfectly (????)
I followed the recipe and my slime wasnt very stretchy, it kept pulling apart very easily, I cant figure out why it wont work!
it sounds like fun to make do we need borax or can we use baking soda
Wow, this looks awesome! My grandaughter loves unicorns, so this might be right up her alley.
You need to add more activator
While searching for the cheapest shaving cream, I bought a can of women’s raspberry. I was white and it smells like raspberries. I purchased this at Dollar Tree.
Hi!
Amazing ! This really good idea. I hope more sharing ideas for us.
Hi !
amazing this is a really great idea for party. I hope more sharing ideas for us..

Thanks so much! Yes, it’s really an easy recipe if you follow directions. 🙂 So happy your slime turned out awesome!
can you send me some slime
You are my favriote sisters in the world
Yes can you do that pls
Thank you so much you are so nice.
Can you make it smell like food
How much water do we need to make the slime
How fluffy
how old is she??????
How much borax do we need?
We followed the actual recipe as written (amazed when people change the recipe – for food OR slime, then complain that it didn’t turn out as expected ? ?). Ours turned out terrific, we just had to add lots more borax to get rid of the stickiness. But the recipe suggested that, so we followed it and… Voila! Perfect! (makes sense to start with a small amount of borax water, as described, because you can always add more, but – just like cooking with things like salt or soy sauce – you can’t take it away once you’ve used too much.)
Thanks again for the great recipe! Having it all measured out definitely made all the difference in the world compared to others we’ve tried! Will use this recipe for all future slimes. 10/10 would squish again. ?
Nice work. Keep it up.
This recipe calls for borax. You can measure ingredients by placing ingredients into measuring cups. If you only have saline solution and your slime is runny, try adding baking soda to thicken it.
How do you measure shaving cream?
Used saline instead of borax
All I got was goop – it never solidified
What’s the answer?
Was so excited to make but it did not work
Yes, this recipe works best with borax.
Yes, you can add the color before and it makes it a lot less messy. I hope you enjoy it!
If you put it in a sealed container, it should stay fluffy for a few nights before the party. The shaving cream is the tricky part of keeping this slime fluffy, it will deflate over time. Have fun!
I can’t wait to make this! If I’m only making one color of slime, so do you recommend adding the food coloring to the glue mixture BEFORE adding the activator? I’m hoping to avoid having blue hands, if that’s possible! Thanks for your advice!
It usually stays fluffy unless you leave it out and let it dry

Want to do this for birthday party…. can I make it ahead and let the kids add the color?? How long before time can it be made if it’s possible? Thank you
This recipe for fluffy slime does not work if you use saline solution. It is so sticky and adding more saline and/or shaving cream does not resolve this. I read in the comments that you could add baking soda (not baking powder) to fix the stickiness and it did work but the slime was not fluffy. I’ll bet the recipe works great with borax and I’m looking forward to trying it with my kids.
Saline solution is loads of water with a tiny amount of borax. You’re not avoiding borax by using saline you’re just adding water to.it and ruining the recipe.
I don’t blame you! ha! Worth a try. But glitter would be so much fun!!
We recommend using borax for this recipe. It’s really the best way to make slime. Next time try adding a little bit of baking soda if you use saline solution and it turns out runny.
We tried to make this on the weekend
Disaster with the slime just being liquid and not turning to slime at all
We used saline solution instead of borax but it just didn’t work !! Any advice? Sarah
Yes
It will be the most fluffy the first day, then it will slowly deflate, but it will still be fluffy in five days.
Yes, you can.
Yes
Can i use paint instead of food color
Can I use paint instead of food coloring. I’ve got glow in the dark paint and want to use the paint and add glitter cause I think this would make this recipe over the moon magical. Thanks in advance for the quick response.
Do you think you could add some clear glitter glue to the white and it still turn out? Want to do this at my 7 year old’s birthday party but not wanting to get actual glitter out. 🙂
Right. Our recipe calls for borax and water. Glad to know you can add baking powder to fix your slime if it’s too runny with saline solution.
Yay! Glad you liked it!
The consistency stays the same for a long while after making it. Just make sure the containers are sealed tight.
Wondering how long this would stay fluffy for? We’d like to make ahead for a consumer fair in five days. Do you think if we stored in plastic containers it would last that long?
Thanks in advance for any advice!
This is THE BEST slime I have ever made!!!!!!!
Tried this using saline solution, came out terrible! No matter how much we added it just got stickier and messier, basically like melted marshmallows. Found another recipe that said to add baking powder so we tried that and it worked wonders. This recipe is probably great if using the borax but with the saline it just did not work at all.
Thanks! My daughter will be happy to hear this:-)
You only need water when mixing borax powder.
Hi.. if we use laundry detergent then will we use water???
Hi Kathy – It sounds like you don’t have the correct amount of borax and water mixture. If you add too much activator, it will get hard. So add small amounts at a time until you get the desired consistency. If using something else besides borax, you will have to play around with it by adding more activator until it’s not runny.
This recipe was done with a borax and water mixture which will give the best results. If using Saline solution, you might need to use more than the amount suggested here to activate your glue and turn it into the slime consistency you like best. You know you have added too much activator if it gets hard.
Kids are crying. Would be helpful to get response soon. Thanks.
Terrible results. Juicie and not forming into slim consistentcy. His do we fix it?
Hi Amy I tried it yesterday but it didn’t work one bit I used saline solution please reply I will try again today
Really great slime recipe!!!
No, the water is to mix the borax powder. You won’t need it if you use contact solution.
Oh yes, glitter would make this even more magical! Glad you both enjoyed it!
Great and easy to follow recipe! We added glitter which sent my 8 year old daughter over the moon with happiness!
If I use my contact solution that has the boric acid in it, do I still need to use the water? This is my first time making slime!
Thank you!! We love making this slime too.
Need this now. Amazing!
This is a great idea. Made it and it was very fluffy! Thanks for the recipe.
LOVE THIS…I hope you will consider sharing at my weekly party.
hope to see you there…so trying this!
