We had obtained an example of this year's hot fireworks selection,
called an artillery shell and drove south of town to let off this celebrated
device. It consists of a ball (actually one buys a set of twelve) with
a 30 cm fuze, and a projector tube, mounted vertically.

One 'lights the touch-paper and retires' as the quaint instructions used
to say on the fireworks of my youth.


He didn't retire for a sufficient time.


These artillery shells set off a propellant charge and then explode in a
star burst at one or two hundred feet. (It turns out that most aerial shells
burst well under 500 feet, as one can demonstrate by flying fairly low on
July 4th evening: at 1500 ft., one is invariably looking downwards
to see aerial shells...)
