On Earth, the capillary effect can be seen in fine tubes containing liquid: surface tension pulls the liquid column up until there is a sufficient mass of liquid for gravity to overcome the intermolecular forces. As the mass of the liquid column is proportional to the square of the tube's diameter, a narrow tube will draw a liquid column higher than a wide tube. In space, many things work differently, but not always.
