Cracking water drops caught on camera

Drops of water normally tend to splash when they strike a surface. But what happens if they hit something very cold? It turns out they first freeze and then crack, forming intricate fracture patterns, one of which you can see in the image above.

It was taken using a high-speed camera by Christophe Josserand, Thomas Séon and colleagues at the Jean Le Rond d’Alembert Institute in France. They watched water solidifying as it dripped onto a stainless-steel surface cooled to various temperatures between 0 and −60 °C (Phys. Rev. Lett. 117 074501). Due to the contact between the drop and the surface, the water’s ability to freeze is limited and mechanical stress makes it fracture in a few milliseconds.
