Inspect the fake blood for color and consistency. If you want thicker blood, add more cornstarch or flour, 2 teaspoons at a time. If you want thinner blood, add a small amount of water as necessary.

Add 1 tbsp. of cocoa powder if you want darker blood. Cover the bowl and refrigerate it until you're ready to use it. The mixture should be good for several days. This yields approximately one cup of fake blood. Double, triple or quadruple the ingredients if necessary.

Loosely twist sheets of paper towels. Stuff the sheets into the leggings. Add enough until you are satisfied with the girth.

Cover the bowl. Refrigerate the guts until you are ready to use them.


  • Using cornstarch gives your blood a slightly glazed look. Using flour makes the blood dull. When determining whether to add cocoa powder, consider your use for the blood. Darker blood is generally used for "dead" blood, while brighter blood is used for wounds, cuts, etc.

    If you want to make edible guts, use sausage casing (vegetarian casing is okay) instead of nylon leggings. Cook enough spaghetti to stuff into the casing. Drain the spaghetti and add enough food coloring to reach the desired color. Stuff the casing with the spaghetti. Let the guts soak in fake blood for several hours.


  • Fake blood and guts will likely stain your clothing.
