How do you produce fake blood?

Answer 1

If you are on a low budget, Corn Syrup and Red food coloring would work the best. it's a great combination for low budget movies, class films, or even just messing around with your friends. ---- More:

To make your own fake blood, here are some other methods depending on the type of blood you need (use amounts/proportions according to eye):

Fresh or spurting blood from arteries or flowing from capillaries (like when you cut your finger) is bright red because it has its hemoglobin carrying lots of oxygen in it and that makes it more red. Make it by mixing red food coloring in white (clear) corn syrup.

Old pooled blood gets thicker and darker. Make it by mixing the red food coloring in the corn syrup and then add chocolate syrup.

Older blood that is spattered or not pooled is a little thinner than pooled and thickened blood, so make that mixture as above with the chocolate syrup and then add a little water to thin it.

Fresh flowing blood from veins has less oxygen than arterial blood and it is also carrying some wastes from the body's cells that make it darker. But, it is not blue like is often incorrectly indicated, even sometimes in school. It is darker red but it is a "cooler" shade of red, and that can be made using some blue in the mix. Make it like the pooled blood with food coloring, corn syrup, chocolate syrup and then a small amount of liquid detergent (like dish washing liquid) that is a blue color just to get a glossy darker dirty red.

But, when you add the detergent, you can't use it for blood to come out of your mouth, so instead of the detergent, when you want to have the blood come from your mouth or be on your face, use honey. So what you'll have in your mouth is corn syrup, honey, food coloring and chocolate syrup.

To make alien blood that is green or blue, just substitute the green or blue food colorings for the red.

Fake blood can be made using a mixture of corn syrup, red food coloring, and a small amount of cocoa powder to achieve the desired consistency and color. You can customize the shade of the fake blood by adjusting the amount of food coloring and cocoa powder used.
