Guy Fawkes day on November the 5th is a rather bizarre UK firework celebration of a historical event. It's like Independence day, but with a much more exciting story of treason behind it.
This video shows a bit of the very old technology of popular effects that are still the core principles used in modern displays.
I thought I'd open some fireworks to look inside so you can safely watch without the risks of doing it yourself.
I don't recommend opening fireworks like this as it does carry a risk of ignition with the possibility of causing severe burns and fire. Welder's clothing and a face visor would probably be a good idea if you ever decided to explore like this. Any materials removed should be treated with great care, clearly marked and NEVER put inside sealed containers, especially glass. I recommend against storage of these materials, and suggest either controlled combustion or thorough wetting to render them safe.
The science behind making good fireworks with consistent operation and colours is huge. There's a lot of information about it on the Internet. Although the base materials are simple, the processes of making the final product are not so simple and require some specialist equipment like open ended ball mills. The risks associated with making the materials are also quite high. That said, there is a culture of pyro enthusiasts who do make their own effects and are the reason we have such colourful and technically advanced displays today.

During the video I started talking about an old video I made for my website that showed a medley of firework contents being sprinkled on a barbeque for effect. Note that this was done AFTER the food had been cooked and that flaming bits will shoot out in random directions, so it's not really a recommended thing. Yes, the video really is 320 by 240. How times have changed since 2011.

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
