Sand droplets falling through space

1 decade 5 years 3 months 4 weeks ago

Granular media such as sand often exhibit liquid-like properties. In this experiment, a freely falling stream of sand is filmed by a high-velocity camera falling at the same speed as the sand. One can clearly see the sand forming droplets just like a liquid would, only at a different size scale. It is still not fully understood why the sand behaves like this.
