Titan's Sand

Science Daily: The electric sands of Titan - The grains that cover Saturn's moon act like clingy packing peanuts
summary - Experiments suggest the particles that cover the surface of Saturn's moon, Titan, are 'electrically charged.' When the wind blows hard enough, Titan's non-silicate granules get kicked up and start to hop in a motion. As they collide, they become frictionally charged, like a balloon rubbing against your hair, and clump together in a way not observed for sand dune grains on Earth -- they become resistant to further motion.
