I found this chest in neighbor's trash this morning, and I was wondering if my creature dude could be made to slowly come out of the chest as the lid opens? Creature is made of heavy foam and latex, and I'd have to shave a couple inches off the rear for him to fully fit. Even then, his head wouldn't fully clear the lid. The lid would remain open about 45 degrees, which I'd be fine with....it's like he's peeking outside his box and then gradually comes out to greet his guests/victims.
I only have very limited, beginner experience with pneumatics, having recently completed trash can trauma prop.
Given how little space there is in the chest with him inside, is this idea even possible?
And is it possible for the lid, always open 45 degrees, to only open until 90 degrees yet the creature to keep rising higher? I imagine the lid need not be on any sort of mechanism. His rising head would fully prop open the lid and lid counter weight (if necessary) would keep it open...but then how does lid get shut once he comes back down?
