How do you put an egg in a bottle in an easy scientific way?

Arabiaweather.com - Someone who tries or thinks of inserting a boiled egg into the neck of a bottle may consider it a difficult, even impossible task, but from the point of view of science, it is possible and in an easier way than we might imagine.

To complete the process successfully, all you have to do is set fire to a piece of paper and place it inside the bottle. After that, place the egg on the neck of the glass and you will notice that after a few seconds it started to slide until it settled inside the bottle.

The scientific explanation for what is actually happening is that the hot air expanding inside the bottle will cool down when the egg is laid, so it shrinks and the pressure inside the bottle decreases in relation to the pressure outside the bottle (atmospheric pressure), which pushes the egg into the bottle.
