Create your own fake blood for extra grisly costumes, decorations or theater props. Fake blood can be made from a mixture of ingredients or by using acrylic paint. Realism is achieved by the elements that you mix together, but most of the fake blood ingredients are in your kitchen cabinets. There are many fake blood recipes, but not all recipes are suitable for all projects. The simple base structure of fake blood is made from white corn syrup, which is thick, sticky and binds well with the other fake blood ingredients.

Basic Fake Blood Recipe

Step 1

Place 2 cups of white corn syrup in a small saucepan. Heat the syrup until it is warm, but not hot. Pour the syrup into a glass mixing bowl.

Step 2

Add 2 tablespoons of red acrylic paint, and mix thoroughly. Use more red paint for a darker red color.

Step 3

Add a drop of blue acrylic paint, and mix well. Blue helps bring out the undertones of the red paint; for a little darker blood, use more blue, but add it sparingly. You can also add a drop of green paint to enhance the red color.

Step 4

Add 1/4 cup of smooth peanut butter to the mixture. Mix well.

Step 5

Place a teaspoon of mineral oil in the blood mixture. Stir well.

Step 6

Pour the fake blood into a glass jar. Label the contents with a permanent marker. Cover the jar with a lid and store the blood in the refrigerator.


Use mineral oil to create a shiny blood substance.

Add K-Y Jelly to make coagulated blood.

Oatmeal can be used for added texture.

Use cocoa powder, cornstarch or flour instead of peanut butter as thickening agents.

Add drops of soap or baby shampoo to make the blood glisten.

Fake blood made with acrylic paint will stain clothes and objects.

Handle heated white corn syrup with care. Overheated sugar can cause serious burns.

Acrylic paint is safe for most skin types; however, always test a small patch of skin near the inside elbow or on the wrist before applying fake blood to extensive part of your body.
