It’s impossible to miss the news about coronavirus, but you probably still have lots of questions. What exactly is it? How does it spread? Can I protect myself? In this episode we’ll breakdown what we know about this new virus and tell you how to stay safe.

Plus, we’ll listen to a podcast hosted by two chatty viruses to learn how these germs spread (and how our bodies fight back). We’ve also got a special message from some super tough hand washers.

Plus a Mystery Sound and a Moment of Um that looks at why shoelaces come untied.
