Wicking in a powder
Pascal S. Raux, Héloise Cockenpot, Marco Ramaioli +2
We investigate the wicking in granular media by considering layers of grains at the surface of a liquid, and discuss the critical contact angle below which spontaneous impregnation…
Surface explosion cavities
Adrien Benusiglio, David Quéré, Christophe Clanet
We present a fluid dynamics video on cavities created by explosions of firecrackers at the water free surface. We use three types of firecrackers containing 1, 1.3 and 5 g of flash…
Grabbing water
P. M. Reis, J. Hure, S. Jung +2
We introduce a novel technique for grabbing water with a flexible solid. This new passive pipetting mechanism was inspired by floating flowers and relies purely on the coupling of…
Paramagnetic Leidenfrost Drops
Keyvan Piroird, Baptiste Darbois Texier, Christophe Clanet +1
We present a fluid dynamics video showing the behavior of drops of liquid oxygen, at room temperature. Due to their low boiling point, these drops levitate on a cushion of their ow…
Water spring: a model for bouncing drops
K. Okumura, F. Chevy, C. Clanet +2
It has been shown that a water drop can bounce persistently, when thrown on a super-hydrophobic substrate. We present here scaling arguments which allow us to predict the maximal d…
