It’s no secret that some of the biggest things in human history were discovered utterly by accident. Penicillin and X-rays, to name just a few, are among them.

Of course, it doesn’t mean that game-changing inventions happen that often. And if Fleming returned from his two-week vacation to realize his petri dish had bacterial colonies that wouldn’t grow near the mold, it doesn’t mean two weeks by the sea would give you similar results.

That doesn’t mean we’re not allowed to play with chance and see where quasi-scientific DIY experiments will take us. Below is a collection of some of the most mildly interesting cases, like leaving a summer roll on a desk for 4 days to find it sprouting or quickly switching temperatures on a marble. Don’t ask why or what for—some things are meant to be "just because."
