A champagne cork is made up of several pieces of cork, that are grounded and glued together, like the letter T. It is shaped like a regular cork, before it is put in the bottle. The mushroom shape that you see when you open it, is a result of expansion of the cork by contact with the wine. An analogy would be a sponge that expands.
Well, you can use some sort of corkscrew... or if you don't have that, and you're out camping, say, you can gently hit the bottom of the bottle against something hard and solid, like a good sized tree. That will cause the cork to slowly come out, with every hit. Hit firmly, but gently.
get one of those long toothpics and pluck it out :D
It's smaller when they put it in and then it expands due to moisture in the air.
Originally, it is done by a machine, but once you open the bottle, the cork cannot be put back in.
they are carved and shaped from the cork tree. however, synthetic cork and screw cap (Gilbertson's closures) are also popular wine closures nowadays.
Rabbit corkscrews are used for opening wine bottles. The corkscrew is manually screwed into the cork at the top of the wine bottle for a few turns. Once it has gone in an inch or so, the levers or rabbit ears are pressed down. This pulls the cork out of the wine bottle.

If the wine is an expensive wine, it will probably be ruined by a defective cork. An inexpensive wine will not be helped by a defective cork, but the damage is less noticeable. You will need to use a better corkscrew to remove the remaining part of the cork. You may have to strain the wine to get the bits out. Many taste tests have shown that there is no difference observed in the quality of wine with synthetic corks vs. natural corks. The plastic corks are quite inexpensive and do not break apart. Most wine lovers have an aversion to screwtops, but the fact is that screwtops are as effective at preserving wine as corks.
The purpose of a wine stopper is to cork the remaining wine in a bottle before putting it on a rake or into the refrigerator since using the original cork is sometimes difficult to put back into the bottle.
remove the cork using the cork screw and if the cork falls down into the wine, decant the wine
It keeps the wine up against the cork, which keeps the cork from drying out. When the cork dries out it will shrink and either let air into the bottle (ruining the wine), or fall into the bottle (also ruining the wine).

You pop off the cork on a wine bottle before you can drink it.
The wine goes bad.
Cork is made from a cork tree or cork oak. This is a variety of quercus which is the family of trees including the oak.
The main benefit of a CO2 wine opener is the ease and speed with which you can open a bottle of wine. The opener injects a small amount of gas into the bottle with a needle through the cork which pushes the cork quickly out of the bottle.
It depends on the producer. It can be from a tree or synthetic, or there can be no cork at all.
