Somebody having accidentally stumbled across something that does things you would expect (either not expect from that sort of object/technique, but was otherwise a not surprising thing or an effect you wouldn't expect *at all*)

The "because science" is them not merely trying to figure out what they can do with the effect, but also figuring out what is happening and why.

Reproducibility is nice, but having a workable theory as to *why* X happens will get you a lot farther in the long run.

Trying to figure out what the "variables" are and testing to see what happens when you vary them can be frustrating, annoying, humorous etc.
