Regular price $4.00 Sale

How can one enjoy other planets without fully appreciating our own? This buoyant rock, pumice, is a volcanic rock formed from lava full of gas. Pumice isn’t just that gray block your dad uses to sand down his weird feet--It’s responsible for one of the earth’s most amazing phenomena. Floating islands of pumice result from undersea volcanic eruptions and can span hundreds of miles and sometimes serve as ferries for island/continent-hopping plants and animals.
