Why do things float to the top?

Objects with tightly packed molecules are more dense than those where the molecules are spread out. Density plays a part in why some things float and some sink. Objects that are more dense than water sink and those less dense float. Hollow things often float too as air is less dense than water.

Why do I sink when I try to float?

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.

Can everyone float in the water?

Hicks explained not everyone can float — it depends on body density and their ability to displace enough water to float. People with smaller or muscular body types tend to have trouble. Salt is more dense per volume than the average person, so it is easier to float higher in saltier water than in fresh water.

What types of individuals may have a difficult time floating in water?

People with smaller or muscular body types tend to have trouble. RelaxNSwim further explains fat is less dense than muscle and bones, so fat floats more easily. Salt is more dense per volume than the average person, so it is easier to float higher in saltier water than in fresh water.
