Abstract
The pressure in a Plateau border is calculated from the tatter’s profile measured by light interference, with the objective of better understanding the phenomenon of marginal regeneration. The local pressure in the border, at small heights above the bulk liquid, unexpectedly turns out to be lower than the hydrostatic equilibrium pressure. This can be understood through flows in the border caused by a surface tension gradient at the border/film transition. Such flows in the Plateau/border (upwards near the film, downwards far away from the film) have indeed been observed, by flow visualization through addition of solid particles.
