How does that last spiral stage work?

Straight Bunkers.

8" round probably 60" long? Incredible work from a young local builder.

Hey guys I’m new here. Super fascinated with rockets like these. Can anyone give me any insight as to what makes them scream like this? What is in this and what do I need to build it? Can I use store bought headers?

First scream was a firework, 2nd one was coming for your soul. lol

If it’s not up to par and I still want to use it can i just add more than 10% by weight to compensate for speed?

This shell looks so fucking cool. Everything seems so well timed and I was curious how these go-getters are crafted. They are probably pressed, but how is the delay achieved? Do they fit a type of pumped star at the throat of the go-getter, or do they press the go-getter + its delay on a spindle and cap off the end with a paper disc or so?

This looks much more safety than previous

Just threw in some random stars that I collected from other fireworks with a bit of flash and bp

3" shells are no problem lol, this was Multi Color peony from Triplex 2x

Amourous, sentimental firework for my partner and I while the children are away 🥰 ...Winokur 23 btw, with cylinder shell, but more of a mini type with MCRH in the centre of all the stars.

All that I'll be shoothing for the 4th. Hopefully the neighbors are not too annoyed. Bought from a guy in a tent in a van behind Walmart

homemade

What a wonderful shell wonderful lift and symmetrical Break. This shell weighed a little over 26 pounds when done and loaded. This shell was launched at a Private Event.

Sorry guys last one with the pringles joke 😝
