trying to discuss quantum mechanics with nonscientist audience?

[doulostheos]

I'm going to be giving a presentation which has absolutely nothing to do with quantum mechanics, but I want to use QM as an illustration of my main point. I will be talking about the paradoxical reality of our world and universe. My audience probably doesn't know much about quantum mechanics, so I need some advice on some simple and relatively understandable examples I could use. I want to demonstrate how strange quantum reality is without making their eyes glaze over.
