I live in Warsaw, and I think I was told about those clams in school, and it never occured to me, that this is something weird. So I interpret this video other way around: I just found out, that this thing that I just knew and accepted as a fact might be weird to someone :),(reply>), This is weird to people with an overblown believe, and or trust, in technology. I think it's brilliant.,(reply>), well i think most people think is like some type of machines test it or something, but it kinda make sense to use clams, building a machine that can do all that a clam can do is probly very hard,(reply>), I live in Warsaw and never heard of this ;). Maybe it is something relatively new?,(reply>), @J. Kasprzycki 😄,(reply>), @Wiktoria Rynkun im polish, from łódź, and i also never heard about it, and i was surprised to learn we use this method in poland
