“This is a craft recipe for fake blood. Got a Halloween costume, school play, haunted house, or you feel like leaving work early and you need some fake blood that looks realistic and doesn't taste half-bad? Here it is...”
3/4 cup

Ingredients Nutrition

  • 12 cup warm water
  • 1 tablespoon cocoa powder
  • 3 -4 tablespoons corn syrup
  • 12-1 teaspoon red food coloring
  • 2 drops yellow food coloring or 2 drops green food coloring (optional)


  1. Mix cocoa powder into the water before adding the other ingredients.
  2. After adding the rest, blend well, then wait for it to settle a bit.
  3. Either skim the bubbles and chocolate scum off the top with the edge of a facial tissue, or pour the mixture into another container.
  4. The longer it sits, the more the cocoa tends to settle to the bottom, which oddly mimicks the effect of real blood separating.
  5. If you splatter this mixture onto cloth, it makes neat two-part marks which dry into pretty convincing bloodstains.
  6. If you let it run from a victim's mouth and then let it dry, the blood darkens and cakes to the skin in much the same way real blood does.
