Experimental results for the inclination α _s needed to dislodge a drop of volume Ω, put on an initially horizontal plane of glass that we slowly inclined. Ω ranges from 15 µl to 100 µl. This graph shows that for a glass surface, the scaling law between  and L _c Ω^−2/3 is once again reasonably valid (as it was for a plane of acrylic). What changes, compared to the previous experimental results with a plane of acrylic, is the slope of the fit. This slope is indeed linked to the contact angles between water and the plane, which are different for a plane of glass and acrylic.
