Today, we have one of the coolest experiments you can do with a cloud and a bottle. I think you won't believe your eyes, but you should! We're going to explain all about why this cloud science works and try to think of some different ways to experiment with this cool phenomenon. Why is this important? While finding cool science experiments is so fun, figuring out the actual science behind them is even better. Oftentimes scientists observe funny things like our cloud experiment and have no idea how it works. They then investigate and investigate and end up making world-changing scientific breakthroughs as they learn why. What amazing things will you discover?
