An Alien creature back tube used in the 1986 James Cameron classic movie Aliens. This is an end section of one of the four exhaust pipes from the back of one of the terrifying creatures. This particular tube was attached to an alien in a scene where the Colonial Marines fire on the aliens and blown them up with their blood and guts spraying out. It is made from foam rubber, painted grey and parts of it have a resin coating that is actually the alien’s dried blood. Custom made acrylic display.
