Michael,
I have employed a similar principle following the naval tradition of my late father. As a shipwright on HMS Glasgow he shared the duty of 'bulling the teapot', ie swilling the nearly empty rum kegs with water to extract the last dregs, known as 'bull',a much inferior drink. I promise I am not taking the proverbial.
My big brother, also Michael (not taking the Micky), would bring home plastic canisters one foot cubed (nearly put my foot in it) which had previously contained sherry, from the off licence where he worked in Grimsby.
After the canisters had been duly swilled and the contents consumed in the naval tradition of 'sucking the monkey', the containers were redeployed in an early example of recycling as six 'buoyancy bags' in my 'Gremlin' dinghy.
The moral of the story is that you may get tipsy, but you can still float.
Should I be worried as 'Craic' has no seal to the 'Swallows Nest' side compartments?
Kind regards,
Andrew
