Hello, I am working on setting up a kabuki drop/suck drape set up for a magician who is taking it out on the road this summer. We are just trying to get the one he used to use up and working properly. Problem is I don't feel it is safe to release a sand bag that rigged overhead in a backstage area, and allow it to run free all the way into the deck surface. He says they do it mainly to get a consistent speed as far as the drape being sucked off the stage, so the idea of using any mechanical means to add friction and so slow down the bag dropping is out of the question. I considered using a reverse bungee apparatus but then there would have to be a qualified tech there to be able to handle the rig. If anyone has any ideas I would appreciate the input.
