Where the liquid wets the glass (θ < 90°) surface tension pulls it up a fine tube to height h = 2S·cosθ/(ρga); where it does not wet (θ > 90°, like mercury) the same physics pushes it down. Narrow the tube and the rise grows as 1/a.
Dip a fine glass tube into the liquid.
h = 2S·cosθ / (ρga) = — mm (S = 0.073 N/m, water)
θ < 90° → the liquid rises · θ > 90° → it is depressed
