The document provides instructions for making fake blood and compares different recipes using ingredients like washing up liquid, food coloring, cocoa powder, water, golden syrup, ketchup, and icing sugar. It notes that a recipe using green washing up liquid, red food coloring and coco powder produces quite a thin consistency but an accurate color, while other recipes can produce a good thickness and edible consistency with an edible product that has good color. A recipe using non-edible ingredients like washing up liquid goes foamy or bubbly and separates, smelling bad with a bad texture and viscosity. Proper mixing is needed to avoid lumps.
