What is the point of a snorkel underwater?
A snorkel allows you use to breathe air from above you when your face is underwater. When you dive with a snorkel, the snorkel tube fills with water and you can’t breathe. They hold their breath. Then when they come back up to the surface they blow the water out of the tube and breathe again.
