The Coolest Alarm Clock Ever Had to Forever Go

Long before clocks, humans found creative ways to track time. From falling sand to burning incense, we tried it all. But it took a daydreaming astronomer and a whole lot of inventors to get us to the precise clocks we use today. Joy Dolo and co-host Kira set off on a tour of ancient timekeeping devices with reporter Carla Javier. Plus, we’ll learn about a clock buried deep in a mountain side that’s designed to keep ticking for 10,000 years. This episode is sponsored by StoryWorth (storyworth.com/forever).
