Pumice floats on water. It is because it is made out of lava which had bubbles left inside it. The bubbles has air trapped in it. These bubbles allow pumice to float on water.

Is a marble denser than water?
Yes if it floats. Does Marble float in water? If not then the answer is no.
Does gas float on top of water?
Gasoline floats on water. That is why water is not used on gasoline fires. The fire floats on the water and spreads rather than being smothered by the water.
Does cork float or sink in water?
it floats
Does ethanol float or sink in water?
Floats
What is water called when water rises?
Ice, it rises till it floats.
Which stone never fell down in water but remain on the top of water?
Pumice stone floats on water.
Why a stone sink in water but a ship floats on water surface?
A stone has a greater density than water; a ship, less.
Is a marble denser than water?
Yes if it floats. Does Marble float in water? If not then the answer is no.
Does a real diamond sink or float in water?
A diamond sinks in water. There is only one stone that floats, pumice.
Which stone can't drown?
A pumice stone is a volcano output that is so full of air bubbles and so light that it floats on water.
What stone float in water?
Pumice, a volcanic stone with tiny air bubbles, is the only stone that floats in water.Pumice.Pumice, a volcanic porous stone, is lighter than water of equal volume because of all of the air bubbles in it, so it floats.
Do cattail floats on water?
Yes. It floats on water
Can float on water?
Of course. Fresh water floats on salt water, warmer water floats on cooler water, and ice floats on any water.
Why does a piece of stone sink in water but a ship with a huge weight floats?
The ship is hollow. The stone isn't. The air trapped inside the ship allows it to float - despite it weight.
Can objects of the same weight have different buoyancies?
Sure. A small stone can have the same weight as an inflated party balloon. But the balloon has more buoyancy, so it floats on water, while the stone sinks like a stone.
How does ice floats on water?
It is less dense than water, therefore it floats on water.
Why pumice stone doesnot sink in water?
In short, pumice is less dense than water, so it floats. During the formation of pumice stone, air bubbles are incorporated into the stone itself. These air pockets make the overall mass of the stone much lower than you'd expect, and work like small floatation devices when the stone is placed in water.
