The show we're doing next, Inspecting Carol, calls for the stage-that's-part-of-the-set to collapse near the end of the show. This is not something we have a problem with; the pivot has been designed. Where my problem lies is the designer wants to have dust fly out when it collapses, and all he has right now is a "Bag O' Dust" under the 'stage' that is crushed/opened when it pivots down to collapse. Questions: What should I use for the 'dust'? Whilst we do have a limitless supply of it, mainly on top of the house fluoros, I would prefer something a little more eye/lung/mouth friendly. How should we release the 'dust'? A bursting Bag O' Dust isn't easily refillable. Perhaps a gravity-based release for a fabricated box? An air-jet propelled piping system all around the set for maximum dust spray area? Hm.
