    Jun 15 2026
    Imagine living on the International Space Station, zooming around the Earth at a mind-blowing 17,500 miles per hour! But what actually happens to your human body when there is absolutely no gravity holding you down? Hosts Mira and Finn are blasting off to explore the wild, weird, and wonderful effects of microgravity! Did you know that if you went to space right now, you would instantly grow up to two whole inches taller? Without gravity to squish your spine, you stretch right out! But that is just the beginning. You'll also learn about "puffy-face, bird-leg syndrome," why astronauts have to cover their food in spicy hot sauce just to taste it, and why drinking water involves catching giant, wobbly floating blobs! Discover why astronauts must strap themselves to the walls like bats just to get a good night's sleep, and why they have to run on special bungee-cord treadmills for two hours every single day. Get ready to learn the amazing science behind how the human body adapts to life in the stars!

We will also follow the famous inventor Thomas Edison on his wild race to create the very first working lightbulb.
