Well done - implode, exactly. It will be the water flask. You will have consumed the hot soup after an hour's climbing to keep yourself warm.
Does this need an RCD?

Isn't it strange how an off the cuff remark unintentionally takes on a life of it's own?
As an aside I'd like to ask some of the experts on water pressure if it might be harmful or distressing for my "flying fish" as regarding any negative pressure .
Some of you remember my "Flying Fish" - two tanks holding water (and several goldfish).
An inverted U tube between the two tanks and full of water.
so the fish travelling up the tube and over to the opposite tank are say 6" (150mm) above the water level in the tanks.
When in the tube they are at negative pressure when compared to water level I would think.
Out of 7 fish, 3 never travelled, 4 did and two of those were "frequent flyers".
The seemed to be more active at flying during warm sunny weather and would stay in the tube together for hours (Set up is outside).
I suppose they do what feels comfortable and avoid what does not but I just thought some of you might know a bit more about the pressure or lack of it.

ah, you didn't mention the drinking the soup bit.
If you had a metal vacuum flask, full of diet coke (other brands are available) sealed it whilst at sea level, then took it up a mountain to an altitude where the relative pressure was now only 50%, how many mentos mints do you have to use to get the flask to acheive escape velocity and fly to the moon? What quantity of diet coke would be needed?
Because the mountain is a volcano, and it gets ******* hot up there.Why would anyone carry a flask of cold water up a mountain.
Funny you should mention that. A few years ago I went on my (only) ski trip to Meribel.
I had a day off skiing and took the lift to the top of Saulire (3000metresish). In my bag was a can of Coke. Somewhere during the ascent it burst, ruining my camera and some other stuff.

Brilliant!
How come I regularly pack aerosol cans into hold luggage for planes and have never had a problem?
PS - these are not the sort of planes which only exist on conveyor belts.

Well the pressure at the top of the tank will be atmospheric presure, clearly the pressure at the bottom of the tank will be higher and that at the top of the loop will be lower than atmospheric. If the loop was big enough you would reach a point where the pressure was low enough that rather than liquid water you would have a near vacum with some water vapour in it.
However given the small size of the fishtank the change in pressure from the top of the loop to the bottom of the tank will be relatively small.
If this was a tank full of murcury the pressure differences would be much higher because mercury is much denser.
Wouldn't that cause the fish some health problems?
Perhaps because aerosol cans do not have a weak point for easy opening, as a coke can does.
When they serve cans of coke etc on planes they are always bulging.
Same with the grossly overpriced pringles - you can see the paper seal on them bulging.
Did you know that the people who make Pringles spent a lot of time and computer power using CFD to design them to the best shape that would allow them to run the conveyor belts fast without the things taking off?
(And no - this is not another plane-on-a-conveyor-belt reference.)
