Materials that climb up vibrating tubes
This effect is not seen in liquids or solids, but because granular materials show both solid- and liquid-like properties the periodic variation in the force between the tube and the particles causes them to climb. The effect is still seen when all the air in the system is removed.
By analyzing the forces acting on the particles the authors present a model that explains the phenomenon and that is consistent with experimental results.
