How do you make fake blood?

Answer 1

Make a thick simple syrup.

1 cup of water and 1 1/2 cups of granulated sugar.

Heat in pot until sugar dissolves and small bubble appear.

add red food coloring until it looks like real blood and cool.

Or, you can make it some of these ways 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 (the lazy man's way of doing the same as the above recipe using granulated sugar and water).

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 makes 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 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.

If you want something cheap and edible that doesn't take much time to make, try this. Crystal Light Raspberry Ice sugar free drink mix. It may sound crazy, but it works. Just mix it in with a tall glass of water (more than 8 oz, less than 42oz), and you're good to go. I scared my dad with it, and he teaches senior high Biology! Note: It will stain skin and clothing quickly and easily. Brush your teeth once and it comes off your teeth fine, but it'll take a shower and a few washings to get off your skin. Clothes may or may not be permanently stained, this hasn't happened to me, so I don't really know. If those factors don't matter, I highly recommend this.
