It requires some empty space to mix so it won't work for everything but will work for many uses."----------Let's be clear to beginners that the method of binary mixing would make building a flash-broken star shell even MORE dangerous than if the flash were mixed by hand outside the shell. The only time binary mixing is safe (in the final effect) is in a flash salute with no stars or other inserts to 'bang it around' while mixing. And...Sparx88 --For a couple of seasons, we played with the concept of "solid-state airbursts" for stage work. No loose powder, no Saran baggie, no anything but a 3/8" diameter ball of solid comp on the end of a match wire. When they worked, they were spectacular and clean. But we found that even the tiniest variations in the quality/age/oxidation/coating of the aluminum fuel could take them from being little atom bombs to being just ugly, dripping slag generators. And we found that no vendor would exert enough control over the quality of their aluminum powder to positively ensure they'd work all the time. So, we eventually tabled the project, and settled for designing a means to quickly and semi-automatically tie Saran airbursts that were more conventionally-made (with powdered fuel).
