Warm several plates in an oven set to the lowest available temperature, until it is warm but not too hot to touch. Put a metal baking tray in the freezer. Mix gelatine powder, water, and liquid glycerin (hand soap) in equal amounts. There should be no sweetener or other additions in any of these ingredients. Heat this in a microwave in 5–10 second bursts, until it is a homogenous liquid. Do not touch it at this stage, as it can cause nasty burns. Take the plates out of the oven. Wearing gloves, pour the gelatin in a thin layer onto the plate. Tip the plate to spread it as thin as possible, then transfer the plate to the cold tray to set it in that thin shape.
For a long cut, keep the tear long but narrow. For a more shocking wound, tear it into a wide, mangled mess.
A non-toxic label does not guarantee the product is skin-safe.
If your fake skin already matches your skin tone well, you can skip this step, or just sprinkle on cocoa powder for a dirty appearance. If the mixture is too pale or runny, mix in corn starch or honey to thicken it. This thicker mixture can also double as fake blood in the steps below.
If you do not have foundation, or if foundation alone doesn’t look convincing, roughly brush on the cocoa powder and food coloring mixture.
Dip a cotton swab in fake blood and let it drip onto the skin around your wound, while holding it vertical. Wet a toothbrush in fake blood and pull back the bristles with your fingers, letting go to spray the wound with blood splatter. [7] X Research source
Never use real blades or shards, even plastic ones, or you could cause an actual injury.
Check the label when buying fake blood. Light-viscosity fake blood creates a more dramatic squirting effect. [8] X Research source
