Hollow things float because they displace a volume of water greater than their own weight. This creates an upward buoyant force that keeps them afloat. The empty space inside the hollow object decreases its overall density, allowing it to float on the water's surface.

How do things float?

things float because they are less denser then the water. second things do not float, the molecules from the water support the molecules from the thing on the water. that is how something heavy can float. it just has to be boyent meaning it is spread out enough so there is more water molecules to hold it up. if you mean in the air it is the same concept.

What are some things that can float in water?

Objects that are less dense than water can float in it. Some examples include wood, plastic, cork, and certain types of metals like aluminum. Additionally, objects that are hollow or have air pockets can also float in water.

Can a concrete boat float?

Yes- because they are not a solid block of concrete- they are hollow with a large air space. The weight of the water displaced is greater than the weight of the hollow concrete hull, and it will float.

Why will a hollow boat made of plasticine float?

A hollow boat made of plasticine will float because the overall density of the boat is lower than the density of water. The buoyant force acting on the boat is greater than its weight, allowing it to float on the water's surface.


Why might metal sometimes float and sometimes sink?

All objects float if their average density is less than the substance that they are immersed in. So if something is hollow, or has a substance lighter than the liquid in it, it would float on the liquid. (Some things are denser than their surroundings, some are less dense)
