comment upon rigidty,container filled with gas?

Think of a helium balloon.

As the air pressure decreases around it, the air, if contained in a flexible enclosure, would expand, pushing the sides of the container outward. IE: a balloon getting bigger. But I'm not sure what you mean by a "parcel" of air.

The gas is turned into liquid by compressing it and well mixed up with water. When we shake the soda it turns back to gas and hence needs more room than it has.

Ack... Munir got here before I did agian.  A agree with Munir!  Volume of any gas at STP is 22.4L.

There are air tight containers and there are air tight containers.  A birthday party balloon is airtight and ok, an airplane isn't.  Location works the same way.  If you blow up your pop bottle in the middle of a gravel pit, and clean up the mess, probably few people would care.  In someones face would be a different story.  The real worry is what are you going to do next?  \n\nI'd say, in the proper setting, your co2 toy sounds like fun and fairly safe.  Go for it!

A real gas is a form of matter that will conform to the sides of its container.  As it is compressed its temperature increases.  It is the only form of matter than can be compressed at all.  Gas is the least organized form of matter.

Depends on what kind of gas you mean.

Generally someone is under anesthesia.  The gas is under pressure before it goes to the patient.  Pneumatic pressure would be important in this.

I know that Gasoline and the Carbon chained fuels separate into water and thicker part after so much time of storage if exposed to air.  If you keep an inert gas in the container you will be okay.  Doesn't go "bad" per se, but just won't burn after like 5 years of free O2.

you're forcing the CO2 out of solution all at once.  because it can only exit through a small opening it seems explosive

think it just  gas, and it will pass

Yes, gravity exists near anything that has mass.  If you remove the air from a container, what's inside won't float.

i think its hydroggen gas burning

Yes.  The methane and hydrogen, the main ingredients, are flamable.  The perfect circumstances?  That's a tough one.  Perhaps if you were a bit stoned so that it would be humorous?
