You will need:
- moulding clay (any type of clay like substance)
- liquid concealer (skin tone close to your own)
- fake blood
- liquid latex or spirit gum
- powder concealer/white cream
- projectile-like object
- super glue
Step one: Start with some moulding clay (I used flesh coloured mouldable earplugs). Roll the clay into a ball, then flatten it into a circle.
Step two: Take the circle and bend in the sides, making a bubble in the center of the circle, so that air is trapped inside it. Press down the sides of the circle around it (it should be a bit wavy on the sides now).
Step three: Press your finger down into the bubble, so that there's a crater in the middle of your wound.
Step four: Making sure your wound mould is on a cleanable/disposable surface, spread some of your liquid concealer onto the wound. Let dry until it is past its tacky stage.
Step five: Afterward, apply your powder concealer, if applicable.
Step six: Put a dab of fake blood in the center of the crater, and tilt it to the side, so that it drips out, to look as if it's actually bleeding. Let dry.
Step seven: Super glue your bullet/bolt/other projectile to the center of your wound. Let dry for specified amount of time.
Step eight: Just before you want to go out, apply the headwound with the spirit gum or liquid latex, conceal the sides with your concealer and/or white make up, and apply another drop or two of fake blood, so that it runs down your natural skin as well.
Step nine: Scare the ever lovin' poopy out of your friends!
