I'm trying to make a stomach burster alien for my costume (late I know, but I figured it would be a quick prop) and I'm having trouble. It's the one that pops out of people's stomachs in the Alien movies. I started with a silicone dildo, cause it was the basic shape and flesh colored and have carved and cut it up a bit. I'd like to add more material to make the back of the head longer and give the sides some "alien" definition, but I can't find anything that will stick to it. I have tried hot glue, silicone caulk and spirit gum. Eyelash adhesive is next. I'm not sure how to adhere it to my skin either if the eyelash adhesive won't work and I need to get some teeth in it. Anyone familiar with working with this material?
