NOTE: If you live with someone else in your house or multiple, ( even better), that are familiar with this movie this is a funny trick. Grab a pair of big scissors or fabric scissors and cut four little holes in a shirt that you don't need anymore. Put the shirt on and in the places were your skin is exposed and put fake blood in the holes, if it drips don't worry that's more realistic. Also if you don't have fake blood just lying around you can buy it here:
Also if you want to do it the fun way here is a link to a recipe for fake blood:
