15 Best Halloween Slime Recipes
These Halloween slime recipes have been kid-tested and are SUPER fun for preschoolers right up to big kids! I know my little girl loves to play with slime, and I am sure yours will too!
Classic Halloween Slime
Let’s start out with something simple. The easiest way to make Halloween slime is to mix two Halloween colours, orange and black of course! These colours show up really nicely because this recipe calls for using acrylic paint instead of food colouring. Add that to the solution of baking soda, contact solution and glue.
Kids just love mixing colours and they will love this Halloween colour slime!
Orange and Black Slime from Ruffles and Rain Boots
Halloween Slime Jars from Best Ideas for Kids
I can’t even begin to say how much I love these Halloween-themed slime jars. Slime plus Halloween decor equals a winner for me!

Although this pairing of green slime and eyeballs is just perfection, this post also suggest other fantastic pairing for slime and accessories, like red slime and vampire teeth! Genius!
Ghost Slime from Steamsational
Another fabulous idea from Steamsational. This Ghost slime activity is half slime, half science experiment. Simply glue a ghost face on a plastic cup, make some clear slime (no food colouring added) and put the slime on top of the cup and let it drip down the cup until it’s covered. SO much spooky fun!
Fluffy Slime
Fluffy Spider Slime from Little Bins for Little Hands
Little Bins for Little Hands has a great recipe for fluffy slime, which has shaving cream added to make it feel so fluffy. They recommend making several batches of different colours to facilitate several different days of sensory play. My personal favorite is this purple slime with spiders. How spooky!

Jack o’Lantern Fluffy Slime from The Best Ideas for Kids

Spiderweb Slime
Spiderweb Slime from The Chaos and the Clutter
This slime recipe uses Instant Snow to change the composition of slime, making it more like a spiderweb texture. This activity is right on theme for Halloween and is so unique!
Spiderweb slime would be great for a child who has already done a lot of slime experiments. The texture of this slime will be so different and will really spark the interest of a child who is a bit bored of slime (if that’s even possible).
Spiderweb Slime from Totally The Bomb
Totally the Bomb shares another great spiderweb activity. This slime recipe uses Styrofoam balls to give extra texture to the slime recipe.
Sparkly Slime
Errupting Jack o’Lantern Slime from Little Bins for Little Hands
Using this sparkly slime to errupt out of a jack o’lantern is such a fun Halloween activity! This activity can use a real pumpkin (it will need to be a small one, or you’ll have to make a ton of slime to fill it), or a fake pumpkin like this one.
Either way, watching slime ooze out of a jack o’lantern will definitely thrill your children! The sparkles in the slime is the perfect spooky touch!

This activity is another winner from Steamsational. Adding eyeballs to this red slime is the perfect yucky addition.
They note that the slime sticks to the eyeballs much like the optical nerve attaches to a real eyeball. There’s always room for learning along with fun when you’re making slime!

Halloween Peeps are even cuter than Easter peeps (in my opinion), so any activity using them is a winner in my books!

This zombie slime activity is so much fun and totally yucky. This is a liquid starch-based slime, and the authors suggest adding extra liquid starch to make the polymers extra long and stringy. This is the perfect texture for zombie slime!
