Can you imagine the law suits if a magazine suggested making a diving helmet out of a biscuit tin today? 'Modern Mechanics and Inventions' advice was 'you are in no particular danger' if you don't go deeper than about ten meters 'for most of your dives'😒Riiiiight...it all sounds like an unnecessarily complicated method of drowning yourself to me...

'Be sure to pick helpers at the pump who don't think it "funny" to quit while you are down below'. Excellent advice, that.
