How to Make Fake Blood

Fake blood is easy to make at home using everyday ingredients. The exact recipe depends on whether you want realistic color, thickness, or the ability to wash it out of clothes.

Simple washable fake blood

This version is best for costumes and short use.

Mix corn syrup with red food coloring as the base. Start with a small amount of food coloring and adjust until the color looks right. Add a drop or two of blue food coloring to darken the red. If you want a more realistic tone, add a tiny amount of cocoa powder.

This creates a glossy, fresh blood look and washes out easily from skin.

More realistic thick fake blood

For film or makeup effects, thickness matters.

• Use corn syrup or honey as the base
• Add red food coloring slowly
• Mix in a small amount of cocoa powder or chocolate syrup to deepen the color
• For older or dried blood effects, add a tiny bit of blue or green food coloring

Stir slowly to avoid bubbles. Let it sit for a few minutes so the color settles.

Matte or dried blood effect

Fresh blood is shiny, but dried blood is darker and less glossy.

Mix red food coloring with water and flour or cornstarch until it thickens. Add cocoa powder to darken it. This version looks more matte and works well for dried blood effects on skin or props.

Edible fake blood

If the blood might go near the mouth, use only food-safe ingredients.

• Use corn syrup, red food coloring, and cocoa powder
• Avoid any paints, detergents, or chemicals
• Always label it clearly so no one mistakes it for real blood

Safety and cleanup tips

• Test on a small patch of skin first
• Avoid light-colored fabrics unless the blood is washable
• Store in a sealed container in the refrigerator for short-term use
• Discard after a few days if it smells or changes texture

Final note

The best fake blood is slightly darker than bright red, not neon. Realism comes from subtle color adjustment and the right thickness for the situation.
