We put water boiled in the bottle

 

                                             We put the boiled egg on the mouth on the container

                    

 

As the water cools and the vapor condenses the egg begin to deform

and to enter the neck of the container 

                                                           The egg falls inside in the bottle.                                                      

                                                           It doesn't break.
