Air Knife Creates Smoke "Screen"

This customer designs and builds special effects for haunted houses. For one particular effect, they wanted to project an image onto a screen of smoke. Using a Model 2636 36" (914mm) Full-Flow Air Knife, smoke was introduced to the back of the Air Knife, where it was entrained. The laminar air flow from the Air Knife provided a uniform wall of smoke on which they projected images of ghosts and goblins.
