Copernicus Buoyant Rock

Pumice is a pretty cool addition to any mineral collection. Get yours with this Copernicus Buoyant Rock!

Pumice, a very light-colored, frothy volcanic rock, is formed from lava full of gas. As the lava hurtles through the air during an eruption, it cools, and the gases escape, leaving the rock full of holes.
