The cork used for wine comes from trees. The one used for champagne is actually the same, but it is made of two pieces that are put together, and inserted into the bottle. Its mushroom shape happens after it has been inserted, due to its exposure to liquid. Cork is like a sponge, and will absorb liquids, and therefore expand. This doesn't happen in regular wine because the neck of the bottle is not as wide, but it is still though to open a bottle.
the bottle will land in her lap
You could get struck in the temple and it could kill you if it was being popped out of the bottle. It could plug your air pipe if you swallow it. The Starship Enterprise could teleport it into your heart. That would be bad.
The bottle will collapse when the bottle has heated air
The bottle will land on the interstate behind the car.
The air will rise into the upper bottle in bubbles while the water splatters and drips down into the lower bottle. No vortex is formed.
Different things can happen if a bottle is placed gently on flour. If the flour is all spread out on a counter, then the bottle will leave prints in the flour. If the flour is packed tightly, then it is possible for the flour to be able to hold up the bottle.
It will implode.
