I show how to make cheap, safe, and edible fake blood that can be used for Halloween, film making and many other purposes. Making your own fake blood is fun, inexpensive and only takes a few common ingredients. The consistency and color of the fake blood may vary, depending on the ingredients and what it is being used for. Cornstarch is added because it will give the fake blood a little opacity and help thicken it to get it to the right consistency. If the solution is too thick, add a tablespoon of water and mix the ingredients. Keep doing this until the blood is the perfect consistency. When you're mixing up the fake blood, it's important to remember that what you see in the mixing bowl is not what the blood will look like on your skin or dripped onto a piece of fabric.

Theatrical blood or stage blood is anything used as a substitute for blood in a theatrical or cinematic performance. For example, in the special effects industry, when a director needs to simulate an actor being shot or cut, a wide variety of chemicals and natural products can be used. The most common is red food coloring, often inside small balloons coupled with explosive devices called squibs.
