i was just wondering if there is any money to be made out of selling flexible plastic tube to smokers - long enough so you could put your fag in the end and smoke it out of the window but from the comfort of the snug with a pint, in a kind of elongated style of an elegant 1930's duchess. I suppose you would also need another one to breath out of .. Reckon the stuff you use for wine making would do the trick..
Perhaps there is a market for those big old fashioned underwater diving suits? That'd do the trick.
