There are dozens of methods for making fake blood. This fake blood recipe takes less than 10 minutes to prepare and allows you to adjust the color and consistency for the most realistic-looking blood. The recipe requires red fruit punch, red and green food coloring, corn syrup, cornstarch and chocolate syrup.
Mix the ingredients
Pour 1/2 cup of fruit punch into a blender. Add 1 cup of corn syrup, 2 tablespoons each of red food coloring and cornstarch, and 1 tablespoon of chocolate syrup. Blend for 10 seconds, or until thoroughly mixed.
Test the color
Use a ladle to scoop out a small amount of the fake blood. Let a few drops fall onto your skin, clothing, props or wherever you intend to use it. Avoid dripping the fake blood on other surfaces, as fake bloodstains can be difficult to remove.
Adjust the color, consistency and transparency
Make adjustments to the mixture until you achieve the right look. If the fake blood is too thin, add 1/4 cup corn syrup to the mix. If the blood is too watery and transparent, add 1 tablespoon of cornstarch. If the red is too bright, add another tablespoon of chocolate syrup or 3 drops of green food coloring. After you add the extra ingredients, blend for another 10 seconds. Test the mixture again, and continue to make color adjustments until you achieve the desired look.
