Why do i sink when i try to float?

This is, in short Archimedes’ Law. A human submerged in water weighs less (and is less ‘dense’) than the water itself, because the lungs are full of air like a balloon, and like a balloon, the air in lungs lifts you to the surface naturally. If an object or person has a greater density than water, then it will sink.

Why do boys swim faster than girls?
