edible fake blood

How to make fake blood with tomato sauce?
I only have a few basic ingredients in my pantry (and I specifically have peanut butter and tomato sauce) and I want to make real-looking fake blood. I don’t need it to look edible, just realistic in photos (for a school project).
Can anyone suggest any recipes that don’t require chocolate sauce? Thanks.
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:
1. Inexpensive white corn syrup is said to be thicker and more suitable for the fake blood than its costlier relatives.
What You Need:
* 1 c (250mL) peanut butter
* 1 qt. (1 L) corn syrup
* 1/2 cup (125mL) soap
* 1 oz (30mL) red color
* 15 drops blue food color
