Another word for a vacuum bottle would be flasken.
It will become vacuum sealed, and opening the bottle will cause a sudden release of low pressure, where higher pressure air from it's surroundings is 'sucked' into the bottle, equalizing the pressure.

That's a weird question, but here goes. Light a couple of matches and put them in bottle. I assume in your case it would be a beer bottle. Quickly place the boiled egg over bottle opening. The burning of the matches will convert the oxygen in the bottle to carbon dioxide, creating a vacuum and sucking the egg into the bottle. Another way is to stick the egg in some vinegar for an hour. Vinegar will soften the egg so it can easily slide in. You could also put water in a pot and let it start to boil. After the water is heated take the water and put it into the glass bottle and quickly put the egg on the top of the bottle. That should compress the oxygen just as good as a match could. You should get the same reaction if done properly. You can also bring the egg out by putting some baking soda on the egg and pouring some vinegar in the container.Quickly turn the container upside down.
This question is a bit too vague, but I'd venture to say that there is a vacuum in the bottle, which sucks the egg in.
There is a silvering in the vacuum flask in order to reduce the loss of heat through the means of radiation.
