I'm working on a build for a short film, that is basically a large, human sized worm. It needs to remain reasonably cheap, so I'm considering building the main form out of carpet foam, and coating it in latex.. Though I'd love to hear any suggestions of how to do a similar thing, but have the creature be transluscent. (my only thought there was silicone, but that would get so expensive it's likely not an option.)
I'm mostly wondering if anyone has suggestions for practical methods to make something like that "breathe".. have considered a bladder of sorts, with an air mattress pump, though it might be too loud..
Also needs to have weight, so that when picked up, it will wriggle, and flop in a semi natural way..
