Here’s What the Fake Blood You See in Movies Is Really Made Of

If you're in the mood to step up your Halloween costume game, here's some bloody inspiration from the greats.

Fake-bloodJoe Prachatree/ShutterstockIf you’re a fan of scary movies, you’ve probably seen your share of fake blood. (If not, we don’t blame you—and neither does science.) How do film crews make the creepy concoction?

Well, a video from the American Chemical Society recently dove into the sticky science of it all. There are actually many different recipes that various filmmakers have used over the years to put the gore in gory. Things like color constraints and budget restrictions have led to a few different mixtures.

Firstly, fake blood was used onstage for years before it was used onscreen. A Parisian theater famously mixed carmine pigment, glycerol, and a thickening agent to create their fake blood. As cinema gained popularity, though, things changed. Famous thrillers like Psycho and Night of the Living Dead had to scrap this recipe after the discovery that it really wasn’t effective in black-and-white. Alfred Hitchcock’s choice for that famous Psycho shower scene? Chocolate syrup!

A mixture called “Kensington Gore” set the standard for red-colored fake blood with its use of sugary syrup and food dye. Horror classics like Evil Dead (one of our favorite horror movies of all time) and Carrie used a recipe that you can make yourself! If you want to try it out this Halloween, it’s ultra-simple. Corn syrup, non-dairy creamer, and food coloring are the only ingredients you need. Celebrated makeup artist Dick Smith put a twist on the corn syrup recipe with a preservative called methylparaben. This mixture added the ick factor to the film The Exorcist. (Did you know that the director of The Exorcist witnessed a real-life exorcism?) The basic corn syrup-based recipe has stood the test of time and still features in films to this day.
