On hot summer days, few things feel better than floating through cool water, whether you're swimming, are using a swim ring, or are in a boat. But did you ever wonder why you can float in water, but a rock can't? Why can't you float through the air (that would be cool!) but a balloon can? This month, we'll be looking at floating. You'll learn what floats and what doesn't, and why.
