Dinosaur Pee?: Crash Course Kids #24.2

Today we continue our exploration of the water cycle by drinking some dinosaur pee. Yep! Well, it's a little less gross than it sounds. It turns out that all of the water on Earth is just constantly recycled in what we call a closed system. No water comes in and no water goes out. So that means that, at some point, it's possible the water we're drinking was once dinosaur pee... or tears...
This first series is based on 5th-grade science. We're super excited and hope you enjoy Crash Course Kids!
