Here is a goofy layman explanation: -particles have variable density and gravity. -particles rotate. -slits create multiple paths. -particle rotation + variable density and gravity makes particles choose multiple paths. It's an explanation which is totally based on macro observations, as if particles where balls with a small heavy object in them, thrown out in multiple tracks. The initial configuration is random, the balls will roll into specific tracks, but since all outcomes are equally possible, over time the distribution of the balls will be equal for all tracks.
