Attachment of a particle to a pendant drop: How large can we go?

Small solid particles can be attached to an air–liquid interface due the pulling of surface tension. We investigate experimentally under which conditions a spherical particle pendant drop, varying density and diameter particle, as well size liquid drop. demonstrate that depending on drop size, largest is limited by two different mechanisms, either falling from nozzle together with or separating bottom Moreover, we show for smaller volumes suction Laplace pressure dramatically increase maximum supported. Finally, propose theoretical model each these regimes explain remain
