Quite a small traditional 4-nozzle tourbillion. Skylighter 3/8" x 2 3/4" 2 oz rocket tube. Ti Driver composition, wax treated cat litter end plugs.
Paddle pop stick, glued on with hot-melt glue, and redundantly tied on with spiking twine. Blackmatch matching between all four 3 mm nozzles, slurry primed. Masking tape over the match to implement piping so all would light nearly together. Blackmatch fuse.
Worked great.
It was a bit of a hack, construction wise, but it performed quite well for its small size. Nice effect, with final burst.
I think a longer tube would provide longer burn-times and greater altitude, but it would also make it heavier and might require hotter propellant. I just loved the larger 1/2" tourbillion, so I think I'll have to repeat that, and add some garniture.
