pumice (a volcanic rock)
Pumice.
A stone will sink in water because its density is greater than that of water. This means that the weight of the stone is heavier than the weight of the displaced water, causing it to sink.
Pumice is a type of stone that floats on water due to its high porosity and low density.
Pumice, a volcanic stone, does not sink in water.There is one type of stone that won't SINK in water.....pumice.
Well I don't know the specific geological name, but it's any type of stone that has air pockets in it.
Pumice stone does not sink in water unless it has been floating for many years.

A stone sinks in water because it is more dense than water.
It is more dense than water, and [presumably] it is not shaped in such a way that all of its weight can be displaced before the stone submerges.
it's because the density may be greater than the body of water that is why the stone sink...
A pumice stone is light weight due to numerous trapped gas bubbles that can cause it to float on water.
