Liven up your disguise as an undead thing—add fake blood!

Here are some non-toxic/edible recipes to use for wounds, splatters, and other ghoulish effects.

Tips:

• Remember that real human blood is thick and dark. Fake blood that is thin and trans­parent will look, well, fake. But don't go over­board on the syrup—real blood isn't that sticky, either.
• A toothpick or the back of a pen is great for applying the blood to specific locations (such as in wounds).
• Edible fake blood should be used immediately or refrigerated. You want to look like you're wounded or dead … not smell that way (or taste rotten fake blood).
• All variations may stain clothes permanently. The corn syrup blood will likely stain white or light-colored clothes, but usually washes out of denim and dark clothes.

Non-Toxic Blood

•   Combine 1 part water with 3 parts corn syrup.
•   Add red food coloring and mix gently by shaking or stirring.
•   Continue adding drops until the shade resembles that of real blood.
•   Add a small amount of blue food coloring to achieve a more realistic shade.
•   Add a thickener.

• Dry thickener: Add sifted flour or cornstarch to your mixture, and gently mix it all again. You may get small lumps forming at the top of the mixture. Wait about a minute and they will float to the top where you can remove them.
• Wet thickener: Stir in chocolate syrup until the desired consistency is reached. It will also add a realistic brown tone to the blood.

•  Let the mixture sit for ten minutes in a warm environment. This will give it some time to thicken.

Note: this recipe yields blood that is initially very sticky, especially in hair.

Chocolate Blood
This mixture looks great, smells great, and tastes like chocolate!

• Combine light corn syrup with red food coloring until you get a shade that closely resembles real blood. (You can also use a red drink mix instead of red dye, but this changes the flavor.)
• Carefully add a small amount of cocoa powder to the syrup mixture to darken the shade and make the blood opaque like real blood.
• Finally, you can either thin the blood by slowly adding water, or thicken it with a couple pinches of flour or cornstarch mixed in carefully and slowly.

Jelly Blood

•  Microwave 3–4 bottles of glycerin.
•  Add one cube of strawberry jelly and mix thoroughly.
•  Add 1/5 of a packet of gelatin.
•  Add red food coloring.
•  Stir until thoroughly mixed.

Use for large wounds to simulate blood clots. Splatter it on your walls for a Dexter theme party!
