fake blood recipe
Nice project to do together
Details
1 package plain gelatin or 1 package red colored Jello
2 bottle red food coloring (especially if using plain gelatin)
1 tbsp green food coloring
1 - 5 gallons of water, depending on desired thickness
Preparation:
Follow the instructions on the side of the jello package, but double or quadruple the amount of water needed, and don't add any sugar.
Doubling the water gives you a very slimy, gloopy jello which doesn't look a lot like blood, but can be fun to get kids to stick their hands into at hallowe'en parties.
If you use 5 gallons of water, you're going to have quite a thin runny blood, great for pouring over bloodied bodies in bathtubs or splashing on walls (especially if you can hose down the walls after - I wouldn't recommend this in your livingroom or parent's bedroom).
You can play around with the recipe to get the desired consistancy - gelatin is reasonably cheap and available in almost any grocery store.
Then take a bath in blood
