Punice is a pretty cool addition to any mineral collection! Pumice, a very light coloured, frothy volcanic rock, is formed from lava that is 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. Pumice is so light that it actually floats on water.
