anyone here use a magnifying glass?
i tried to make something that Archimedes (yes the same guy who ran through the streets naked shouting "Eureka")invented when sicily was under attack and he had to destroy some boats.
Archimedes then took about two score or so of soldiers, and polished all of their sheilds, until you could look at them like a mirror, then he had all of the men make pretty much a solar cookerby pointing all of their sheilds at one boats particular sail.
Holy macaroni!
the sail set aflame and the attackers didnt even know what smote them, the hand of God?!?, or maybe just some crazy smart man who thought that if sunlight were focused, they would burn things?
maybe leprechauns told him to burn things lol
