Can you get an Egg into a Bottle?

Is it really possible to get an egg into a bottle? It is, and here is how you do it.

Drop three lit matches into a glass bottle that has a narrow neck (a 600 mL bottle works well.)

Quickly put a peeled, hard-boiled egg on the mouth of the bottle.
The egg should squeeze its way through the mouth of the bottle and get inside it.

What happens you may ask? The lit matches heat the air inside the bottle. When air is heated it expands and takes up more room. As the heated air expands, some of it escapes out the bottle. When the matches go out, the air inside the bottle cools and contracts (and takes up less room), and this makes the pressure inside the bottle less than the pressure outside. The greater pressure outside the bottle sucks the egg into the bottle.
