Around the 4 minute mark of the show a series of white "flares" shoot up in a fan pattern. What are those called and are they available in a consumer form? They remind me of a bunch of single shot roman candles. Also could it be daisey chained in a series with an increasing delay in the wicks from the e-match to create that pattern of shots? I think that would be a cool effect for a neighborhood 4th show i'm already planning for next year. The Zambelli's do something similar for Thunder over Louisville only they use rainbow colors. Boo52 can u help me out?
