    What happens if you drop a feather in space?

    What happens if you drop a feather in space?

    In space, will a feather stay still? Fall down? Float away? Turns out, the answer depends on where you are! But one thing affects your feather no matter what: gravity! So Galileo is joining us all the way from the 1500s to fill us in on his theory about gravity. Then, we’re heading to space, and dropping a feather in a few different places to see what happens. Listen closely for a listener-submitted mystery sound, and a moment of um that answers this question: If you pick a flower, fruit or vegetable, is it still alive or is it dead?
