Ancient snacks and dirty undies

Today we’ll visit an Australian cave to check out some ancient snacks, we’ll learn about an endangered frog baby boom, and we’ll meet a rising star in the world of fashion. Speaking of clothes, we’re going to dig up the dirt on an item of clothing that people have been burying in their backyards. Finally, we’ll join a group of history hunters who are on a mission to make the world-wide-web a fairer place.
