Just wondering has anyone ever done a miniature display? Something like making cakes that have 1/16" tubes, 1/32" rocket tubes, mini pinwheels, 1/4" ball shells (talk about micro stars). It would have to be filmed with a quality camera to get the effects; if any would work.

Flying fish pinwheels are super fast to make and the different colors make them interesting.

I've made a couple fuse rockets, just wrapped some foil tape around a pice of fast visco fuse with foil fins. They move quite quick.

I wonder what the smallest tube you could use to reliably launch and ignite a crackle granule would be? Would a longer tube allow enough time for ignition to begin before the tiny lift burned out?
Love pondering smaller things for backyard/weekday pyro fixes!

I have made quite a few small rockets out of nothing more than 1/4 - 3/8 thin wall tubes like paper soda straws and the like.  The trick is to insert the drift that fits the tube up about 1/3 of the way up into the tube, then use another on the top side to add whatever you want for the header/stars/whatever you think might work after it gets into the air and lightly press with hand pressure in increments as far as you want to go.  Then fill the bottom with finely granulated hot BP not pressed,  but just poured in to give the tiny rocket some inital first thrust, but not rupture or burn out the wall of the thin tube.

 

Fuse, then wrap and glue a turn or two of thin paper around the bottom and secure with a clove hitch to form a paper 'choke' or nozzle, so to say, to the size needed.  I used weed stalks for sticks.

 

It takes as many 'speriments as the big boy rockets to get them to fly right,  but costs next to nothing to make one,  and is a fun project that lets you smell the smoke, gain experience,  and have fun in a small area.

I think there are a few people who practice from time to time in small or miniature versions.

Patrick, did our Californian brethren do some of that not to long ago? Just maybe not as small as we're talking here.
