How will you remove a crumpled paper inside an empty glass without holding the glass and the crumpled paper inside the empty glass?

Hear the fiendish answer:

Get someone else to move the glass for you. Take the paper.

The trick is in the wording of the sentence. All you have to do is to find a legal loophole.

This is not just some stupid answer, if you look at the question closely enough, you might get some very useful info, like the glass does not have to be upside down. Or the environment in which the problem is set is special. Or it does not have to be you who moves the glass, etc...

I would get a pitcher of water and fill the glass to overflowing. The water should carry the paper out.
