This results in a non-toxic, realistic stage blood.

Here's How:
1. Mix creamy peanut butter with a sufficient amount of white corn syrup to make a runny mixture.

2. Add (non-sudsy) soap and food colors and mix well.

3. Stir more corn syrup in until the desired consistency is reached.

4. Refrigerate unused blood in an airtight container.

Tips:
Inexpensive white corn syrup is said to be thicker and more suitable for the fake blood than its costlier relatives.

1 c (250mL) peanut butter
1 qt. (1 L) corn syrup
