Not sure if this has been asked before, but I just remembered that in the movie What the Bleep Do We Know, a scientist(?) mentioned that an experiment exists, where a visible-to-the-naked-eye object appears to be in two places at the same time.

I was wondering if this is indeed true, and if it is, how is this possible? As in, if it is true, could you explain the set up of the experiment, and exactly how you would make an object appear in two places at the same time.


Thanks.
