So how does it works? The answer is all about air pressure. If you set the egg above the bottle, the air pressure inside the bottle matched the air pressure outside, so nothing happened. But if you drop a burning match inside the bottle, it caused the air inside to heat up and expand rapidly. The expanding air pushed the egg inside and escape from the bottle, that’s why the egg vibrating. When the fire consumed all the oxygen inside the bottle, the flame went out and the remaining air in the bottle cooled down.
