Reading about these kinds of experiments always fills me with lots of little questions like "well what if we did THIS" or "what if we tweaked THAT slightly". I have the urge to try and "catch reality out", to expose the trick. Makes me wish you could do these experiments with a laser pointer and a piece of paper instead of needing lots of very expensive machinery and a research grant. Everyone should have the chance to play around with quantum weirdness.
