Our saviours : In the ninth century, a team of Chinese alchemists trying to synthesize an "elixir of immortality" from saltpeter, sulfur, realgar, and dried honey instead invented gunpowder.

Strangely I don't care what the break height is! I just care that it's close enough to be interesting but high enough to be safe.

Let us know how you get on with it. I assume that you stand a certian distance from the launch site and trigonometry does the rest.
Phew that was close.

But a firework rocket won't go straight but will curve. Will this affect the results much? I quite fancy one.

So long as you knew your distance from the point under it's apache it would be fine, but yep I agree rockets would be a little harder than shells.
I do not intend to tiptoe through life just to arrive at deaths door safely!

Even if your rocket curves a bit, you'll get a rough idea, unless you're using banana sticks and it flies to timbucktoo.
