Here is the corrected text: Raw Pumice Specimen - Single Sample, 1"Pumice forms from the frothy lava created by a volcanic explosion. As the frothy lava cools, it hardens into a lightweight rock filled with small gas bubbles. Because this rock is so porous and light, it can actually float on water. Perfect for demonstrating the effect of vesicles on rock density, as well as for lessons in identifying and classifying igneous rocks.While each specimen will vary slightly in shape, size, and color, it will measure approximately 1" in length. Each is individually packaged, labeled, and barcoded for easy identification and storage.Selected and Processed by a GeologistEach and every specimen is selected and hand-processed by an actual geologist, ensuring that each sample exhibits defining features.
