Hi there! Imagine you see a big whale swimming in the ocean. When the whale comes up to the surface, it needs to breathe just like we do. But instead of using a nose like us, a whale has a special hole on top of its head called a blowhole.
When the whale breathes out, it pushes air very hard from its lungs through the blowhole. This makes a big splash of water and mist shoot up into the air called a 'spout.'
And guess how high this spout can go? It can be as tall as a building with 3 floors! That's like the height of three big houses stacked on top of each other. Isn’t that amazing?
So, the whale's spout is like a giant water fountain that helps the whale breathe fresh air when it visits the surface. Cool, right?
