Alex.. that's a red flag in front of a bull, right there.

Don't expect a christmas card from my partner any time soon.

I'm very conscious of the legal ramifications of such an activity, so I would be curious to know how the 'establishment' might view such an endeavour?

That being said, if cap'n plod were 'appy with it, what I would do.... and this is taking it to it's illogical conclusion... would be to use acetylene (more carbon in the gas) and increase the oxygen ratio to the physical strength limit of the drums. I expect a stoichiometric mixture of O2 - C2H2 would have a blast wave that would shred the drums like tissue, so you would have to turn the dial back a bit under 9 on the 'naughty speed-ometer' Or...if we make the assumption that your intention was to take your strides to brown town?, just use chlorine gas as the oxidant... many fits and giggles to be had with that option.

Rather than have a tube of drums welded together, I would be inclined to stack em, one on top of another with the lids intact other than a fuse hole to pass the ignition up the column. 6 bangs (and a bit of chaos) for the price of one.

Letting that dragon off the chain would get your pulse up past 70bpm, I'd wager..
