Heres something to ponder....?

I'm one for a good brain teaser from time to time, but I alos like to make them. Heres one to think about: A hole is an object, and there fore exists. But a hole is, well, nothing, right? So how can nothing be something? Simply. A hole is a lack of nothing. And before anyone says 'a hole has matter in it in the form of gases" I know that, but unless you think about it for a few second, or give it to the slow kid, it will confuss people!
