NEW VARIATIONS ON THE SOAP FILM EXPERIMENTS OF PLATEAU - 1 - EXPERIMENTS UNDER FORCED DRAINAGE

We have explored a variation of Plateau's wire experiment, in which so ap solution is continually added at the toy of a wire frame, resulting in the displacement, distortion and eventual. instability of the equi librium configuration of soap films. In the case of a cubic frame, an eightfold vertex of Plateau;borders (corresponding to a twelvefold int ersection of films) can be created in this way. We also observed the p assage of a 'triple bubble' along a Plateau border when a single drop is introduced at the Plateau border junction.
