OT: my poor poor flask. Physics expert needed!

I go into my truck to get my flask out, so i can take it on my trip tomorrow (no i do not drink and drive) It has been there since i bought it almost a month ago. Now those of you who know about flasks, know it has a rubber washer type thing in the lid to keep the alc...er liquid in it. :rolleyes:
Well i pull it out of my glove box, where i hid it in my owners manual folder thingy. I pull it out, and the entire thing is caved in on itself. It ouldnt have been crushed because there was nothing else in the glove box. Could the 100 plus days in texas play a part in this? I havent even used it once, and i already lost it. Im sad. Some one please offer me some sort of reasonable explanation.:(

not a physics expert by any means but ...
That flask looks like it caved in due to a change in internal air pressure vs the surrounding air pressure.
If you had it open during an extremely hot day, then capped it, and it cooled at night, in theory it could collapse on itself if the temp/pressure changed enough.
If you happened to drive up into the mountains or down into a valley, while these temperatures were changing - the results would be even more dramatic.
Same thing can happen to any closed container when exposed to extreme temp or pressure changes.
Once it cracked though - it would no longer do this.
If the flask did not have the cap screwed on tightly - then I suppose it was due to just the heat alone .... but I doubt it.
Just an idea ...

Thanx Broomer! Thats what i was lookin for, I just needed support for my theory.
And Lesa, dont worry about the drinkin and drivin, One of my friends was killed by a drunk so, i have witnessed first hand the effect of it. :(

It looks like it may of overheated, then cooled quickly.
Word of caution; Drinking & driving covers boating also. Just like automobile accidents most boating accidents involve alcohol. That said, When I was 19 I used to go to Hawaii where I could legally drink.
Take care!

If the flask contained some small amounts of ethyl alcohol - the effect would be even greater as the alcohol changed from a vapor upon heating, then back to a liquid as it condensed. Basically it "could" create a vacuum inside - sucking in the walls until it cracked.

lol! I hate the heat out there. Of course the humidity isn't any better in MD. I think I'll move to the North Pole or something :rolleyes:

can't you just buy a new one...:confused: they aren't that expensive :cool: :D
Cheers! and have a good time!

Unless you opened that thing at 10000 feet, capped it, and then brought it down to sea level, I can't see that much destruction.
Think back...ever keep it in your back pocket?
