If I run the experiment in that video, with the metal balls, I get the same result as if I do it while standing in the room, or not standing in the room. I don't need to observe to get the same results.

Hitting an electron with a photon is NOT observing, it's interacting. You have altered the behavior of the electron. You have not just merely observed it.

And by interacting, you alter.

The word causing the problem is observe. What is more accurate, is interact.
