Earlier quoted context omitted.
Oh man those kvass canisters. So in our area there was an urban legend that once a truck transporting kvass (kind of like a fuel truck) crashed and fell on the side. Kvass poured out and along with it monstrous worms size of a human leg (nobody ever washes those canisters). I wonder if that was possible.
Seems like this would be really bad business just from a transportation perspective. Giant worms take up transit space that could be filled with kvass instead. A quick Google for "giant worms" finds a few that are a couple centimeters in diameter around the world, but none in the vicinity of Russia.
My uncle even made one up with his friends. They went fishing, got drunk and decided to tell everyone they saw aliens land. They had noticed an area by woods that was burnt by a lightning strike and some fire had started. So that became the landing site. And so on. He made us kids and a few women from the village believe him.
There were national ones of course. My favorite was about this: https://en.wikipedia.org/wiki/Kola_Superdeep_Borehole. The rumor was that the scientists had reached hell (temperature increased dramatically, which it did in reality, see! every legends needs a tiny bit of truth there), and there was, of course, a red monster which crawled out from the whole. I really loved that story as a kid.
There were countless others which I already forgot.
