How can i visualize quantum superposition in a double-slit experiment?

I’ve been trying to wrap my head around the concept of quantum superposition, specifically how a particle can exist in multiple states at once until measured. My confusion comes from trying to picture this with a simple experiment in mind, like the double-slit setup. It just feels paradoxical that observation itself forces a definite state.

I tried a dorm room version of the double-slit with a cheap laser and a piece of foil. Before I ever measured anything I kept picturing the photon as being in some limbo, not choosing a path. When the screen finally showed a clean interference fringe, it felt like uncertainty wasn’t a mystery pulled out of thin air but something the setup was actively showing me. Not a coin flip, more like a story that only resolves when you look.

I tell people measurement collapses the wave, and that’s what makes a definite state appear. But honestly I still don’t picture what that collapse looks like in reality. It sounds reasonable in math, but when I try to picture it, I get stuck and mumble about probabilities.

I keep wondering if the real snag is our habit of turning a tiny thing into a little person with intentions. Like maybe the problem isn’t the particle choosing a path but our own intuition about cause and effect. I even told a friend about Schrödinger’s cat just to vent, and then remembered the experiment still says the pattern changes with detectors. So yeah, more questions than neat answers.

One concrete thing I did: set up a detector at the slits and then watched the interference vanish. Counts dropped to two lobes instead of a full fringe. I logged the numbers, saw the change, and walked away mumbling that I still don’t get it.
