As seen in "MythBusters: Breaking Glass"


Explanation: Since ancient Greek and Roman times, people have passed along the proverb that a rolling stone gathers no moss. While taking that saying out for a spin, MythBusters Tory Belleci, Kari Byron and Scottie Chapman ended up conducting the longest experiment in the show's history. For six months, a handful of rough stones slowly tumbled around a rolling rig coated in a buttermilk-moss solution that stimulates growth. A control group of stationary rocks sat glued in place for the duration.

After six long months — and nearly 100 miles — of turning around and around, the rolling rocks emerged moss-free. For comparison, the rocks in the stationary control group sported fuzzy green coatings.

Though it took a long time to prove, the MythBusters clearly confirmed that the ancient metaphor is rooted in literal fact.
