We investigate the interaction that occurs between a light solid cube falling under gravity and a horizontal soap film that is pinned to a circular ring. We observe in both experiments and quasi-static simulations that the final orientation of a cube that becomes entrapped by a soap film is strongly dependent on the Bond number. A cube is...

Aqueous foams are suspensions of bubbles inside aqueous phases. Their multiphasic composition leads to a complex rheological behavior that is useful in numerous applica-tions, from oil recovery to food/cosmetic processing. Their structure is very similar to the one of emulsions, so that both materials share common mechanical properties. In...

We investigate the effects of the contact angle $\theta_w$, and the angle of inclination $\theta_i$ on the interaction between an infinite cylinder and a free fluid-fluid interface governed only by its surface tension. We describe a numerical method to calculate the deformation of the interface, and use it to validate a theory for the force on...
