I love this you tube vid Its very simple and anyone can follow how weird quantum physics really is.

The classic double slit

I love it too, for its simplicity.

A few months ago I've even used it in my blog when trying to post a simple overview about quantum physics:

Actually there were double slit experiments conducted that successfully watched which slit does the electron/photon go through which still preserved the interference pattern. It all depends on how you watch.
See Afshar experiment, for instance.
I think the idea that the particle goes all possible ways is just an approximation because we don't know better ways how to describe that.

Another nice thing to look at is the ultra-sensitive bomb testing problem. It reminds me of zen: observing by not observing.
