Chugalug,
I didn't make myself very clear did I ? Problem is, I can't find fractions yet. Should have said "Four Eleven and a half pound bombs !" - (why don't we forget about the half, just toss for it, and simply call them 11 or 12 lb ?)
But of course you had tongue-in-cheek, I'm sure - if not, idea is: bomb hits ground, goes pop, emits smoke for a minute or two, goes out. Simple.
But not a toy. General rule: smaller the bomb, the nastier.
Camera obscura ? - there's an idea. But CCTV better !
Cheers,
Danny.
