Résumé

The Youtube channel Zeste de science explores all aspects of scientific research, proving that even the most complicated scientific facts can be explained in less than 5 minutes, and that even the most seemingly trivial events of everyday life, if thoroughly studied, can contribute to the biggest technological advances.
Episode 21: What is the difference between quicksand and standard sand? Using a water tank, tiny spheres of glass and a marble, researchers in Marseille have conducted a series of experiments to determine the factors responsible for the compactness of granular materials. They can now understand why sand reacts sometimes like a solid, and sometimes like a liquid. This study could explain some natural hazards and could contribute to the development of new materials.
