I went to the State Fair today with DD15.  My favorite part is the arts and crafts, and all the canned things. 

My stupid question is, Why are all the cans displayed lid down?

It's easier to open that way, because the vacuum is at the bottom (which is currently at the top), because all of the product has settled at the top (which is currently at the bottom.)

Do you have any evidence for that? From a general physics standpoint, it doesn't make a lot of sense. The entire contents of the jar, whether it's the food or the small amount of air, is going to be under the same (negative) pressure. Unless the contents of the jar are very, very thick, the air (not vacuum) will rise to the top when you turn it right side up to open. I'm certainly not going to try to open a jar of pickles or strawberry jam without turning it with the lid towards the top.

Sorry, but that sounds like a piece of folk-wisdom to me.

You don't open the jar while it's upside down... but tipping it upside down and then back does something because it does seem to help "break the seal".  It doesn't work on peanut butter because the air doesn't go anywhere.  But with pickles and salsa the air moves to the bottom and then back to the top but maybe not all at once? Thus the vacuum isn't as "solid" or something? I don't know I just know that it works when I can't just open the jar and is quieter (and safer) than banging the lid with a butter knife or the edge of a counter.

I would guess the display is done that way for 2 reasons: one being able to see the contents of the jars more clearly (like Virg said) and two to make it easier to open and sample the stuff inside.

When I make jam, I turn the jar upside down when I seal it.  This helps achieve the vacuum seal on the canning jars.  If I want to make the seal stronger, I also give them a water bath.  The non-water bath works best with jams and jellies, because the contents are so hot.  Also, I boil the lids, so they are ready to seal.  As the jars, lids, and contents cool, a vacuum is created.  You can tell because when you use the current canning jar lids, they have a "dimple".  As the contents cool, a properly sealed lid will pop in once as the pressure inside the jar is reduced enough that atmospheric pressure pushes the lid inward.  An improperly sealed jar will allow the dimple to move up and down, sometimes making a popping noise.

My guess as to the display, is partially to add another layer of protection from an accidental vacuum break, show off the contents better, but also I'm guessing that the lids have the owner's information on them.

My thought on the physics of turning a canning jar upside down work from the same principle that wine connoisseurs use.  Storing the jar inverted keeps the rubber seal moist (like storing wine cork down) so that it doesn't dry out and let the seal fail.  It won't make much difference in opening the jar, but it will preserve the seal longer, and since canning is done to allow for long term storage it would make sense.

I always it was to make things easier for the judges and present a colorful display for visitors.

Okay, this is making me nuts.  Awhile back DH and I saw an internet joke making fun of those inspirational "quotes about life"-type posters.  The only thing I can remember for certain was that it ended with "here's a picture of a tree" with a picture of a tree underneath.  DH loved it, and I'm hoping I can find it as an actual poster or print or something for him for Christmas.  But I can't remember the full quote, and that's hindering my search a great deal.  Does anyone else know the full quote?  I'm pretty sure it showed up on one of the Cheezburger sites, if that helps trigger any memories.

I thought of another reason-the ribbon string "catches" on the upturned lip of the can and dangles there.  Right-side-up, it would fall to the shelf.

That awful song "All These Things That I've Done" says over and over, ďIíve got soul, but Iím not a soldier.Ē What kind of word play is that? Itís not a pun, right? Gish asked me this morning because we were lucky  ::) enough to hear it on the radio and I really donít know.

Yes, that is exactly it!  Thank you for preserving my sanity!  :D

I'd consider it a pun, because it's taking a rhyme as a definition match.

It's a play on words using homophones.  "Soul"(s-long o-l)  "Sol"(s-long o-l) dier.

But what's the implication?  That soldiers don't have souls?

I'm not familiar with the song but if I had to guess, there's no real implication, just saying "I've got <first half of a longer word that is itself a word>, but I'm not a <the longer word>".  You could sub in other semi-rhyme/semi-homophones with just as little meaning.

If it meant anything, more likely "all soldiers have souls, and so do I." But I agree that there's no actual meaning here--the songwriter just thought it sounded clever. Or, I suppose, is using the words purely for their sound rather than meaning, as some composers have admitted to doing.
Any advice that requires the use of a time machine may safely be ignored.

Soldier can also mean "gangster" or "thug" and soul also sometimes means "street cred" so they could be saying they have street cred (or are well known) but that they aren't a thug/gangster.  Do you remember who the artist was?
