Guess what happened on the Space Station! An astronaut named Don Pettit did a fun experiment. He grew crystals from a kind of salt. The crystals looked very strange and beautiful. They did not look like crystals on Earth!
On Earth, crystals grow in solid shapes. But in space, there is almost no gravity. So the crystals grew in a different way. Their edges grew faster than their middle parts. This created cool step-like shapes!
Scientists are very excited about this experiment. They want to understand how things behave in space. One day, people might make special materials there. Space is full of amazing discoveries to explore!
