What brilliant treasure is hiding inside that small bit of agate? A stunning tiger's eye or a gleaming quartz gem? The Rock Tumbler uncovers the secrets of ordinary rocks-revealing amazing colors and patterns with a glass-like finish! Tumbling is easy: just place a few rocks or minerals into the tumbler with some grinding powder(included). Unlike other tumblers, you select the length of time to tumble; the longer the time, the shinier the rock! The grinding powder duplicates the erosion process that takes thousands of years in nature! Soon you'll end up with a treasure trove of shiny, polished rocks.
