How to Make Fake Blood for Halloween
Many years ago, I worked as a celebrity makeup artist. And for a while there, I trained in special effects makeup—you know, the gooey, gross, and oozing stuff that makes you gasp or peek through your hands as you’re watching a scary movie. If you’re planning a DIY Halloween costume and are trying to figure out how to make fake blood to accent your creation, we’ve got you covered. Literally.
Making fake blood is both creative and easy, depending on your needs. The king of modern splatter makeup, Greg Nicotero, who’s best known for his work on The Walking Dead, once told CBS News that creating fake blood was “kind of—oddly—a weird art form.” He’s not wrong. And Nicotero’s creative zombie art has inspired countless Halloween costume ideas and Halloween makeup ideas.
So why should you whip up your own fake blood? Well, what is Halloween without a little gore? Plus, it’s easy, inexpensive, and really fun to make. And let’s not forget about bragging rights. You can reference it in your Halloween Instagram captions or share a TikTok of you scrolling through Halloween face paint ideas and scary Halloween costumes and then pan out to an image of you stirring up a batch of fake blood.
How to make fake blood
These fake blood recipes are total no-brainers, but keep in mind that a lot of these ingredients will stain your skin and property. And remember: Don’t sacrifice safety for fun. Fake blood that comes in contact with your skin or mouth needs to be edible.
So, what should you expect from this creepy crafts experiment? The DIY fake blood should be slightly runny, like the fake blood in movies. Think Dexter and his blood spatter, and you’ll have an idea of what the texture should look like. Ready to create your own (make-believe) blood? Here’s how:
3/4 cup corn syrup (if you’re trying for the look of old blood, consider using a few drops of maple syrup as well)1/4 cup water1/2 teaspoon red food coloring5 drops blue food coloring2 drops green food coloring1 tablespoon cornstarch
The food coloring proportions are optional; only you know the exact color you’re trying to create. That said, using green and blue makes the color more realistic. Bear in mind that red and blue create purple, and green will give your fake blood the sickening look you’re trying for.
How to make fake blood for clothes
If you’re hoping to make your clothes look bloody, you’ll need to create blood that is thicker and darker. The fake blood recipe below is nontoxic and made with edible ingredients. Ideally, you’ll make a bigger batch of this fake blood so you can thoroughly soak your costume.
This fake blood recipe uses a ratio of corn syrup to water versus exact measurements, so you can make as little or as much as you like. If you and your friends are batting around group Halloween costume ideas, consider making a single batch of blood for everyone to use.

You can also try using old red paint and water, blending in blue and green paint until you have the right color and texture of dried blood.
How to make fake guts
Now that you’re comfortable with how to make fake blood, let’s up the ante and add in some guts. Have you been watching the new season of American Horror Story? Spoilers ahead: A perfect family moves into a town filled with bloodsuckers, and within days, the hot dad is downing a gross smoothie made of raw meat. If you’d like to achieve the same blood-and-guts effect, we have an easy recipe. It’ll come in handy whether you’re creating teen Halloween costumes, adult Halloween costumes, Halloween monsters, or Halloween decorations that are extra creepy.
For the guts:
2 tablespoons cornstarch4 teaspoons water2–5 drops red food coloring1/2 teaspoon cocoa powder
For the blood:
2/3 cup chocolate syrup1/3 cup laundry detergent4–6 teaspoons red food coloring
This blood is not edible and should not come into direct contact with your skin.
You can add gross clumps by using cooked oats, which take dye pretty easily. Or add peanut butter or red Jell-o to the mix. If you’re really committed to your gross DIY adult Halloween costumes or DIY Halloween costumes for kids, you can also include slices of hot dogs sticking out of your pockets or other red-looking meat products for extra ick.
How to make fake scabs
I don’t mean to give you nightmares, but when I was learning how to do special effects makeup, we used a lot of mortician’s wax to get the shapes we liked for scars or scabs. We’d hide squibs (miniature explosive devices that shoot out fake blood) under the wax and then, when someone was (fake) cut, the blood would shoot everywhere. Good times!
Want to create your own fake scabs for your solo or couples Halloween costumes? Here’s an easy recipe. But if you have sensitive skin, don’t even think about trying this. And if you’re hairy, you might want to consider shaving the spot underneath your DIY scabs.
For the scab:
Liquid latexTissue paperEyelash glue (optional)Foundation that matches your skinFake blood (made using one of the fake blood recipes above)Coarse brown sugar
Another slightly more pricey trick is to use silicon scar-healing gel. Apply a bit until it dries and then blend in fake blood until it looks lumpy and scabby.
There you have it: super-creepy (yet surprisingly easy) instructions for how to make fake blood, whether you’re planning costume ideas for men, women, or children.
