Inside the massive International Space Station live astronaut scientists from different countries. Every day, they conduct one fun 'space science experiment' after another. Because the space cabin is in a wonderful state of weightlessness without the constraints of Earth's gravity, many fascinating things happen: for example, a lit candle flame actually shapes into a cute, perfectly round little ball! Sparkling water droplets can hover quietly in mid-air like magic balloons. Scientists carefully tend to little plants in space to see how they sprout and grow without gravity, and they also test all sorts of amazing new materials. Sometimes, plant seeds from elementary school students are sent on a 'space trip,' and then brought back to Earth to be planted alongside regular seeds to see whose sprouts grow stronger!
