This is one of my favorite movies of all time. 

The Wonkavator is used in Willy Wonka and the Chocolate Factory movie. At the end of the movie Wonka and his two guests get in the Wonkavator and blast through the roof of the factory. As the Wonkavator floats high over the city, Wonka tells Charlie that he was looking for a successor to run his factory, and that the Golden Tickets were all part of a test to find a good and worthy child to fill that role. Wonka tells Charlie he was looking for a child rather than an adult, so as to have an open-minded student. As such, Charlie and his family will move into the factory, and (eventually) take over its operation. Wonka warns Charlie of “the man who got everything he ever wished for … he lived happily ever after,” as the Wonkavator sails off into the sky.
