About this episode
If everything was the exact same color, would we still be able to see? Why can't I take naps in contacts? How long does it take to get to space? What would you bring to Mars? How many people are asleep right now? If atoms are mostly space, why don't I fall through my chair? Hank and John Green have answers!
