I saw someone else comment about this, and I can't verify the accuracy of their assessment, but according them the science is a little off. The observation that is used that makes the interference pattern go away is not passive. It is the methods of observation that is causing the change in behavior, not some conscious effort by the particles themselves.

I've seen that video before .. the overhead animation of the wave interference is good, but doesn't match with the interference pattern that they show on the back wall. Details like that drive me crazy. Still, it's an engaging video and educates .. so overall, it's great.
