A short video with the Japanese showing off their shell-building skills. Some nice examples here:

One thing that baffled me as a child was how the stars in fireworks, the colored projectiles that are thrown from the shell when it bursts, could disappear then reappear in either the same color or a different one. This confused me almost as much as when I asked my father, at about the same age of 6 why James Bond didn't need the oysters.
In You Only Live Twice, James Bond thought he was going to be sharing a bed with Kelly Suzuki but when she made it evident they would not, Bond pushed aside his oyster dinner and said, "Well, I won't need these". I can't tell you how much that messed with my mind not knowing what the heck oysters had to do with a man and woman sleeping together. Asking my friends at that age got me nowhere of course. That aside, back to the stars.
The answer is the stars never go out though they appear to do so. The star is still burning but at a lower temperature and also a lower light-output which makes the star disappear. This composition is called a dark composition meaning it burns with minimal light output making it burn dark. Say a star starts out as red then disappears and reappears as white, then disappears again and comes back blue.
A star like that would have a blue core, the last color you see in the sky then upon that a dark composition is rolled. By rolled I mean the blue cores are tumbled in a star-roller, misted with moisture which most likely contains some kind of binder, then the dark composition dust is introduced to the star-roller. The moistened blue cores pick-up this material and build in size. Once done with the dark composition the next color, white is introduced. Once white is done another layer of dark composition gets rolled on and then the final color, actually the first color you would see, red is rolled.
That gives you a shell which bursts into red stars traveling through the air which then disappear for a split second changing to white then disappear again only to finally appear as blue. This is a very simple explanation as to how this is done. In reality, much more is involved which has to do with the ignition temperatures of the various compositions and being able to successfully transfer fire from one to another. That process is called step-priming
Geez, I really went off on this post. Wrote more than I intended. Bottom line is the shells shown in this video take this color-transformation process to a whole other level. It takes a crazy amount of time and precision to make shells like the ones you see in this video.
Have a nice week everyone, Pierow
