So my school is doing Beauty for our next musical and we've devised this for the transformation scene. I heard of using white-outs from a las vegas LD but I've never tried it myself. Just looking for some critiques or perspective on our idea. Any suggestions? What our plan is to get a certain pyrotechnic effect for a shielf of sparks to go off. Immediately afterward, we flash lights aimed at the audience, giving a "white-out" effect along with some sort of loud noise. We don't have the means to try it yet and my concern is that too many of our lights will be used just for the flash and that it may not work in blinding the audience long enough to do the change. We may build a trap-door to do the change itself. Any suggestions/advice? Thanks!
