Pumice is a grey volcanic rock so full of gas bubbles that it is able to float on water.
Most igneous rocks are denser than water, so they do not float. However, some types of igneous rocks, such as pumice, can contain trapped air bubbles which make them less dense than water, causing them to float.
Pumice is a very porous igneous rock that is so light that it can float on water. It is formed from volcanic eruptions and has a frothy appearance due to trapped gas bubbles during its solidification process.
Pumice the only common rock that floats in water. But flotation is a technique often used in the processing of rocks for lab study. For this, very dense fluids are used such as polytungstates, or some heavy chlorinated or brominated liquids. Some of these have a relative density of 3.
The description oof it is big grains and there are visual and you can touch them always remember that it is intrusive igneous rock not extrusive rock igneous rock. and the color of it is GRAY!!!! Thankz for asking the questions ask more

Pumice is such a rock.
The rock comes from a volcano and is known as pumice.

I would expect a light gray igneous rock to be rich in silica. Light gray color in igneous rocks is often associated with high silica content, which is typical of felsic or granitic compositions.

Pumice is an example of this
