it has holes in it and has kelfrigis

one. Pumice.
No rocks float, irrespective of color with the exception of pumice, a solidified lava froth.
Pumice rocks have been known to float across oceans.
The extrusive volcanic rock pumice can float on water. Other extrusive volcanic rocks are not so lucky.
Pumice is a type of rock that can float on water due to its high porosity and low density. It is formed from volcanic eruptions and is commonly found near volcanic regions.
Pumice stones will, these are low density rocks formed by volcanoes
Floating rocks: pumice. Non-floating rocks: all but pumice. Pumice can float on water because its density is so low, due to trapped bubbles of air which formed during its solidification from lava.
Pumice is a rock that will often float. It has so many air bubbles in the rock that it is buoyant, especially in salt 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.
Very porous rocks such as pumice can be very light and have the potential to float on water. Pumice is a volcanic rock.
