Measure ingredients into blender. Get a blender, measuring cup, and spoon. Measure and add each ingredient to the blender. This mixture will create a fake amount of blood that you can consume and eat. You need: ^{[1] X Research Resources}

½ cup of red juice
1 cup corn syrup (or golden syrup)
2 tablespoons red food coloring
1 tablespoon chocolate sauce
2 tablespoons cornstarch
1 tablespoon cocoa powder

Blend fake blood until smooth. Cover the blender lid and give it a quick 30 seconds to blend the ingredients and create a smooth fake blood. It is more effective to stop after 15 seconds and grind one more time. Thus, the cocoa powder and cornstarch that are lumpy will be finely ground. ^{[2] X Research Source}

If you don’t have a blender, you can use an all-in-one blender.

Adjust the color of fake blood. Open the blender lid and stir the spoon into the fake blood to check the color. Sprinkle some fake blood on a white tissue for better visibility. If you need to adjust the color, you can add red food coloring, chocolate sauce, or cocoa powder. ^{[3] X Research Sources}

For example, if the fake blood is too pink or pale, add a few drops of red food coloring and blend again. Or if the fake blood is bright red, add some chocolate sauce or flour and continue blending.

Fake blood thickener. If you want to thicken the blood to flow slowly, add a little corn syrup. To make the fake blood thicker, double the amount of corn syrup. Note that you will need to add more food coloring as it will be diluted. ^{[4] X Research Sources}

If you don’t want corn syrup, you can substitute it with golden syrup.

Make edible fake blood with sugar

Measure the water and granulated sugar into the blender. Pour 1 cup of water into a blender or multi-cooker. Measure out 1.5 cups of granulated sugar and put it in a blender. ^{[5] X Research Sources}

Grind water and granulated sugar. Cover the blender, blend the water and sugar for about 30 seconds. Sugar will dissolve completely in water. ^{[6] X Research Source}

You need to grind the mixture to dissolve the lumps of sugar.

Add red food coloring and cocoa powder to the blender. Pour 2 tablespoons of red food coloring into the blender. Cover the blender and blend until evenly colored. Add 1 tablespoon cocoa powder and grind one more time. ^{[7] X Research Sources}

The cocoa powder will thicken the fake blood and make it appear more real.

Make edible fake blood with flour

Put the water and flour in the pot. Take a small pot and pour 1 cup of water into it. Add 1 tablespoon of flour to the water and stir to dissolve any lumps. Try to dissolve the powder in water. ^{[9] X Research Source}

If you don’t have a whisk, you can use a fork to stir the water and flour together.

Heat the mixture. Turn the stove to high heat and cook until it boils. When the mixture boils, reduce to medium-low heat. At this point, the mixture is just simmering. Simmer the mixture for about 30 minutes. Turn off the heat and wait for the mixture to cool. ^{[10] X Research Source}

Boiling flour and water will thicken the fake blood.

Stir in food coloring. Pour 2 tablespoons of red food coloring into the cooled flour and water mixture. Stir in food coloring until the mixture is evenly colored. ^{[11] X Research Source}

You can add red food coloring to make the fake blood lighter in color.

Things you need

Measuring cup and measuring spoon
Blender or all-in-one blender
Paper towels or plates
Plastic bottles for chili sauce (optional)
Small pot
Whip egg beater

Advice

Use a toothpick, chili sauce bottle, or brush to smear fake blood on people, objects, or clothing. You can also put fake blood in your mouth and let it slowly drain out.
