If you want a realistic fake blood, you're going to have to do better than dyed water! Here's a recipe for a realistic fake blood that pools like the real deal and has a better blood color. It's sticky and will stain (like real blood), so use it on washable surfaces or those you don't mind getting all bloody. The blood is edible, so you can drink it if you like.
- 2 tablespoons white corn syrup
- 6 drops red food coloring
- 1 drop blue or green food coloring
- 2 teaspoons cocoa powder
- little water, if too thick
If you use cocoa mix, like for hot chocolate, you'll get a paler blood that may require some water to dissolve the sugar. Unsweetened cocoa produces a better blood for most purposes.
Make It Disgusting
You can sprinkle in some dried onion if you want the blood to look like it contains bits of scabs and fingernails. Other kitchen seasonings add interest, too, or consider adding potato peels. You can splatter the blood either by flicking it on a paintbrush or off of a fork.
