Glow in the Dark Alien Temporary Tattoo Aliens have been a topic of conversation since the introduction of science fiction. Humans are fascinated by the idea of life on other planets, and the rounded head with a pointed chin and elongated eyes is a recognizable portrait of how many believe aliens might look. Popular movies and television shows about aliens have furthered this interest, and many people now choose to tattoo their bodies with images of aliens. Some believe that the tattoo symbolizes feeling alienated or separated from others. This temporary tattoo practically glows in the dark, and is a fun way to dress up for Halloween or show your belief in life beyond Earth.
