huh? the link only confirms that fireworks were invented in china.
getting objects to move with steam (what was apparently invented by
Archytas [in] Tarentum is certainly not similar to fireworks or
rockets. waterworks, perhaps!

Not soHaving watched fireworks at several places, incl the famous

(Fireworks - and all sorts of noisy explosive gimmicks - are still very
popular in Naples, especially at midnight on new year's eve.)
