Myself I'd use a pneumatic cannon, since I have one, rather than a crossbow.



A crossbow is, shall we say, more English, although perhaps historically, a longbow might be more significant.

Was that the same Boys who invented the Boys camera used to take lightning photographs? It's a sort of rotating drum streak camera.
