Science Festival at PMMH


The PMMH will be present at ESPCI (10 rue Vauquelin, 75005 Paris) on Saturday afternoon, October 4th, for open-access experimental demonstrations.
The laboratory will also welcome school groups on October 7th and 8th.

The laboratory tour will be divided into workshops providing a quick overview of the PMMH’s research activities: wave propagation, kirigami, walking drops, tear propagation, soap bubbles, a mechanics workshop, dragonfly flight, superhydrophobic surfaces, and inflatable structures. The workshops or experimental demonstrations have been designed and will be presented by the researchers (non-permanent and/or permanent) or technicians who study them daily.

Each school group will be divided into small groups of 6-7 students to allow for their exploration of the laboratory. Please consider the appropriate number of chaperones.

Grades: elementary to high school.
Registration required by following this link: https://fetedelascience-scolaires.sorbonne-universite.fr/home/actions/VoirFicheAction/3006

Asymmetric bending boundary layer: The λ-test

In this paper, the MecaWet group investigates the mechanics of two asymmetric ribbons bound at one end and pulled apart at the other ends. They characterize the elastic junction near the bonding and conceptualize it as a bending boundary layer.... (...)
