The thing is to blend two pictures together in order to prepare flat image of a human head. Afterwards, the photo has to be laminated and placed in a jar filled with fluid to create the illusion of a decapitated head. This nasty prank was prepared by Instructables’ user, mikeasaurus, who advises to personalize the gag for the best effect.
If you dare to use this horryfing idea, let us know about the reaction of unfortunate late-night nibblers below the post. We hope it won’t be too much for them though.
