/cgl/ - Cosplay & EGL

Okay, got a complicated one here. I'm looking at doing a costume that has a beetle shell and wings. We've done mockups of how to lift the outer shell, but there's just one major problem, my hands won't be available. While most of the more crazy logistics in this costume are handled, I REALLY want the shell to open and the wings to pop out. Once again, just a simple matter of pulling a rope, but hard to do when my hands aren't available to pull said rope. So I was wondering if anyone had a way that would be available via either a switch or something that could lift the shell on said costume.
