Space Adventures: Astronauts Play with Water Coloring in Zero Gravity

Playing with water in space! That's what astronauts do on the International Space Station (ISS). Recently, NASA astronaut Don Pettit created a stunning 'Jupiter-like planet' using water and food coloring. He shared a picture of this colorful creation on a social media platform. Pettit is not stopping there; he plans to make a jack-o'-lantern for Halloween! Water in space behaves differently than on Earth. In microgravity, water forms perfect spheres because there's no gravity pulling it down. This is similar to how water collects into a sphere on a spinning merry-go-round.Companies are also interested in how fluids behave in space. They want to improve products like shampoo and medicine. NASA is curious too, as fluids are vital for systems that purify water and air on spacecraft. As astronauts spend more time in space, understanding fluid behavior becomes more important. For long-term stays on the moon or Mars, scientists need to make spacecraft systems more efficient.
