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.

∙ 13y agoThey are called "Pumice" stones. It's got air [or some kinda gas, probably CO2] trapped in it when it was formed. And that's why it floats..

∙ 9y agoWith porosity of 90 percent, pumice floats on water. It has no crystalline structure and the density varies depending on the solid's thickness.

Why doesn't a stone float?
The stone is heavier than the same volume of water. In short the density of the stone is more than the water. So the stone does not float on the water.
Does a real diamond sink or float in water?
A diamond sinks in water. There is only one stone that floats, pumice.
Can you make a stone float on water?
There are two ways:Hollow out the stone to the form of a boat so that has more displacement then weight.Use pumice, a light weight volcanic stone that has lots of air bubbles in its structure.
Why stone sink into water?
A stone is more dense and heavier than water, so it sinks. If you were to hollow out the top of the stone into a shape like a bowl, it would then be mostly filled with air, and might float. That is the same idea as with boats - even steel boats float if they are hollowed out to where they are light enough. I have even seen competitions to see who can build the best concrete boat.
Why does a stick float amd a rock sink?
It is becase a stick is less dense than water and a stone is much more dense than water.

What is the name of the stone flote on water?
A stone that can float on water is a pumice stone. Ejected from a volcano, and full of holes, it has been known to float.
Is a marble denser than water?
Yes if it floats. Does Marble float in water? If not then the answer is no.
Does lode stone float?
No. To get them to float they must be placed on something light.
Which stone never sunk in water?
the stone that never sunk in water is pumice. Because of its holes it can float easily across the water.
If the stone sinks in water is it a real diamond?
Diamonds do not float.
What stone do not sink in water?
A pumice stone is light weight due to numerous trapped gas bubbles that can cause it to float on water.
Why cant stones float in water?
The molecules in a stone are packed together more tightly than the molecules in water-- the stone is more dense than the water is, so the stone sinks.
Will stone float on oil?
No. Only pumice (volcanic) stone can float.
How dense is a tiny stone?
That depends on the material of which the stone is composed. Some stones are so light that they will float in water e.g. pumice stone, while most others will sink in water.
What stone can float on water?
Pumice stones will, these are low density rocks formed by volcanoes
Does a real diamond sink or float in water?
A diamond sinks in water. There is only one stone that floats, pumice.
