Source: World Wide

Chemical: Lava

Crystal System: None

Formation: Highly porous rock from cooling lava flows

Properties: It floats in water. A floating rock! As seen in the photograph at left. One on a table top, and second floating in water. And it is used for many purposes...from a rather famous hand cleaner to landscaping. Which is where I found this specimen shown at left....in a flower bed around a streetlight in Naples, Florida. Thanks, guys!
