OK, back to the subject at hand. We know it is the Xmas season, and the Pet Rock may seem like a tempting gift for a friend or loved one. But remember
that these pets required long term care, and that of the many Pet Rocks that were adopted during the past several decades, many, many of these once
cherished pets are still around and, tragically, are now delegated to confinement in their boxes placed in a lower dresser drawer somewhere. Before
you place yet another one of these would-be adoptees under someone's care, do contemplate their ultimate fate. The best course of action would be to
query all your friends, acquaintances and coworkers if they have adopted a Pet Rock in the distant past, and if they would please consider allowing it
to be placed under someone else's care if the Pet Rock is no longer a prominent part of the family. Like Mohandas Gandhi once said, to paraphrase,
"You can judge a society by the way it treats its animals." And I believe that Pet Rocks fit into this equation. One last thing I would like to add:
Although it may add an exotic air, I would refrain from taking wild rocks from the Baja California wilderness. They are better off left in their
native habitat, and we have so many neglected ones here at home.

I think you are on to something good. A rock shelter, where people can come to adopt granite, sandstone, basalt, or just plain old roling stones.
Mick and Kieth might be good names for some of these pets.
That B in front of your name is for BOLD, as in a man of boold ideas. No error on my part-- I meant to do that!

I believe his statement included man as well.
Strange from a man who lived in a Caste system.

I am in total agreement with you. Our pet rock is a member of our family and will remain on display in our china cabinet till my children some day
have the responsibility of deciding it's fate. I didn't think to add it to my trust, I'm hoping they won't argue over who gets the honor of absorbing
it into their family.
Our rock has tiny fossils in it. I do keep it seperated from our baja rocks, as we haven't brought any of them up to the states. They perfer to live
at our places down there. The climate is better.

I believe that much of Gandhi's outlook is from his ultimate reaction to the caste system. Here is an interesting Internet article about Gandhi and
the caste system: http://www.bfg-muenchen.de/caste.htm
Dennis, I would like to mention here that I was in no way disparaging you in my response to your question about Head & Shoulders in the thread
titled "Yum Yum" in the Off Topic forum. I was merely in a whimsical mood.
I would also like to take this opportunity to query whether the carbonation would last longer in a partially filled two-liter bottle of a carbonated
soft drink beverage if the sides of the bottle were to be squeezed prior to replacing the twist cap as to minimize the amount of air in the bottle.
Would this be the case? Any information on the issue would be appreciated. Thank you in advance.

Well no wonder!
Now I feel guilty. Maybe I should take it back to it's native land.

Packoderm...If you can convince me you truly do not understand carbonation, I may be able to help...Has to do with how gas is held in supension...do
you remember that Raccoon hat???

Lets me off the hook. I've never been accused of holding gas in suspension.

I researched this a bit and found the following: Coke like all "soft drinks" is carbonated with carbon dioxide (CO2)a clear, colorless gas. The CO2 is
dissolved in the water and sugar mixture under pressure. When the CO2 level just above the liquid is lower in concentration than the CO2 level in the
liquid more gas comes out of solution than returns to the solution. The CO2 is lost from the soft drink. When the cap is put onto the bottle the CO2
comes out of solution until the CO2 level above and within the liquid are the same. This is called equilibrium. Shaking a closed bottle of soda will
cause the pressure to rise because the CO2 is not in equilibrium anymore. After some time has passed the pressure will drop back to normal because the
free CO2 will dissolve back into the liquid, regaining equilibrium. If the soda bottle is half full and the cap is returned to the bottle, the CO2
will come to equilibrium using some of the CO2 from the liquid to do so. The larger the space above the liquid the more CO2 will be required to reach
equilibrum. If the cap is left off, the CO2 level will come to equilibrium with the atmospheric CO2 levels (which for this discussion are quite
low)and the coke goes flat. If you squeeze the space out of the bottle before you put the cap on, the amount of CO2 needed to come to equilibrum will
be less and the drink will keep its fizz. There is one problem with this approach though, when you squeeze the bottle and cap it, you create a partial
vacuum. The CO2 level in the space is very low but the pressure will rise when the CO2 comes out of solution. This should inflate the bottle back to
its initial shape and volume. Since the partial pressure of CO2 is all that matters, not the pressure of N2 or O2 from the atmosphere, the amount of
CO2 removed from the liquid will be the same in either case. If the bottle is constrained so that it can not expand then the squeezed bottle will have
more fizz later.
So, to answer my own question, the carbonation would last the longest if the bottle was squeezed and kept squeezed.

So, users of 2 liter bottles would benefit from the invention of some kind of girdle that would put and keep a squeeze on the bottle. This doesn't
seem like it would be that hard.

On a closer read I was right the first time...Wrong...at least from about half way down...Some how you got lost about the raccoon cap.

Yes, my son, and it is only fitting that we should reunite on the NOMADS BOARD. I have been wandering aimlessly in Utah for decades looking for you
in the red rock country, and now I discover you have been hiding out in Baja-----oh well, we can discuss that later----I guess I was confused.
Good to hear from you, son. Just where in Utah are you now?

Packoderm...it works the same as the Raccoon hat...you relieve the pressure and you lose the gas...Do you know how hard that was to type...

Are you meaning that that wouldn't keep the soda carbonated the longest because not to open it in the first place would have that effect? I would at
this point like to stipulate that the bottle first being opened would be integral to the experiment. Would the coonskin cap serve as a transporting
device that would keep the bottle from being jarred thus resulting in the freeing of the carbon dioxide from the liquid?
