It is made so that it does have atoms that are able to absorb (or inelastically scatter) the photons. If there is no detector, the Em wave will extend towards the screen beyond the slits, and interact with the atoms in the screen. So it took all paths. If there is a detector, it interacts with the atoms in the detector, but until the detector, it took all paths. | |

The laser has the ability to direct the Em wave in a certain direction, so it starts extending towards the slits. As it reaches the slits, the slits are made of a material, that has surface atoms that do not (have little probability) absorb the photons. So the EM wave keeps extending beyond the slits without interacting with the atoms on the slits. | |

Guys did you watch the full video? It implies completely different thing(IMHO). The measuring detector DO NOT change the patter, instead what matters is whether or not we know the exact path of the photon! This is the elephant in the room and of course what is the most non-common sense experience | |
