More weird science! Today’s subject is the Castillo de San Marcos, whose walls “ate” cannon balls! This one is definitely wacky, so I don’t want to spoil the read. Summary courtesy of Atlas Obscura, but they do link to the journal article (which should be free to view) if anyone is interested in some mechanical stress test data (and come on, who wouldn’t be???)
