Serious question, did anyone else think the 'Viking sunstone' thing was total nonsense?

I always figured it was just a cool myth, but then I read a paper from the University of Rennes where they actually tested a piece of Icelandic spar crystal on a cloudy day. The thing totally works as a navigational aid, which is wild. Has anyone else had an artifact theory they were totally wrong about?

Remember when I called that a dumb story for years? Yeah, I'm eating my words now.

Look at old weather rocks, the ones in a little wooden house. People said they were just junk, but the idea is the same. What other simple things did our grandparents use that actually worked, @river952? Like using a pine cone to tell if it's humid, or watching how animals act before a storm. Makes me want to go check all the old farmer's almanac tips.

Yeah, I get that feeling. I was right there with you calling it a fantasy for the longest time. Seeing actual tests with the crystal change its light on a cloudy day was a real eye opener. Makes you wonder what other old stories might have a real trick to them.

Man now I'm sitting here staring at my grandma's old wool blanket trying to figure out if it really knows something about the weather that my phone doesn't. I caught myself last week actually checking a milkweed pod to see if it was fluffing up before a rainstorm and felt like a total fool when my neighbor walked by. But then it actually opened up that afternoon so who's really the fool here?
