It's simple to create realistic-looking fake blood out of flour or cornflour.

Steps

  1. 1
    Grab a big mixing bowl and a mixing spoon.
  2. 2
    Get as much cornflour/flour as you want to make your fake blood. (Cornflour and flour will both shrink in size when you add water, so use more than you think you need.)

  3. 3
    Add enough water to make the mixture dribble- but not watery-consistency.
  4. 4
    Add red food coloring or orange and pink. Add only a drop at a time until you're happy with the final color.
  5. 5
    Mix everything together. Mix until it is very smooth, without lumps. If the blood doesn't look realistic then add in some bicarbonate of soda (baking soda); it'll froth but let it settle and it will work!
  6. 6
    Use as required. This will stain, so only wear with clothes you don't mind getting permanent red stains on. Done!

    To make dried blood just use glue. Dye the glue with red food coloring and dry it out. This will stain if it comes in contact with your clothes.

    You can, but the consistency will not be quite right so it won't be as realistic.

    Depending on the quantity of red tint you use for the blood, yes, it will probably stain.
