buoyancy
An object that displaces its own weight in water is said to be "floating".
An object floats on water when the buoyant force acting on the object is greater than the weight of the object. This buoyant force is exerted by the water displaced by the object, pushing it upwards. Objects that displace more water than they weigh will float, while objects that displace less water will sink.
The density of the human body is greater than that of water. This means that when you step into water, the water you displace has a weight equal to your weight. If you weigh more than the weight of the water that you displace, you will sink.
Objects that weigh 1 gram include a paperclip, a US dollar bill, and a small LEGO brick.
Objects weigh less in water than they do in air because of the buoyant force exerted by the water. This force counteracts the weight of the object, making it feel lighter or even weightless when submerged in water.
An object has to push the water out of the way (or in other words, displace water) in order to become submerged; the weight of that displaced water creates an opposing force called buoyancy, which pushes the object upward, out of the water.

They weigh less than the water they displace.
It is not impossible. Ships do stay afloat. <><><> While they ARE heavy, they weigh less than the water they displace.
Weigh the amount of water he can displace.
The Joke: Not much it sank The truth: A floating boat will displace the same weight in water that it weighs. So the real question is how much does it displace or how much does it weigh
they don't
Objects under water seem to weigh less but they have the same mass as they would out of water.

Objects weigh less in water than in the air because water exerts an upward buoyant force on the object, partially offsetting its weight. This is known as buoyancy, which makes objects feel lighter in water than in air.
