Lunar soil in containers (IMAGE)
Caption
Anna-Lisa Paul tries moistening the lunar soils with a pipette. The scientists found that the soils repelled water (were hydrophobic), causing the water to bead-up on the surface. Active stirring of the material with water was required to break the hydrophobicity and uniformly wet the soil. Once moistened, the lunar soils could be wetted by capillary action for plant culture.
