 * 4) The egg will be sucked into the bottle and remain fully intact.

What Happened - and Why? By not letting any air into the bottle (by sealing the egg to the bottle), while air is leaving the bottle, you have created a vacuum inside the bottle. A vacuum is what is created when there is no pressure. By having a hole in the egg, you released some of the pressure but not enough pressure to let the egg come out. By Putting the match in the bottle the warm air expands the bottle and the vacuum forces the egg inside of the bottle.
