It was used to navigate on the sea and on unexplored land. It works by using magnetic rocks (lodestone) that align north. This is signifcant because it allowed for expanded trade and exploration during this time period. I chose it because I still use the invention whenever I go camping. ]]> 2017-04-25 18:18:30 UTC https://padlet.com/marcouillerk/2yiwbzfbksxx/wish/168198469
