Interesting about quiet fireworks:
quiet fireworks can actually be more colourful. All fireworks are a balance between “colour-producing material in the shell versus the kaboom-producing material,” … quiet fireworks don’t need as much kaboom, they have more room for colours.
Yorrike I've only known about Quiet fireworks for 5 minutes and I’m already outraged they're not in universal use.
Miraz Jordan @yorrike Likewise, I'd never heard of them before. I'd like public purchase of fireworks banned in NZ, but quiet fireworks would deal with at least the noise problem.
