The bacteria that turns water into ice

It all has to do with ice nucleation — the process that forms ice crystals in the atmosphere and, thus, snow. You probably know that raindrops and snowflakes form around something. There’s always a central nucleus that serves as the backbone of the water molecule structure. Usually, when people talk about this process, they use soot or some other kind of particulate matter as the example of what a nucleus can be. But bacteria can also become the nucleus of a snowflake. In fact, P. syringae is so good at forming ice crystals around itself that, in the video above, you can watch it turn cold water into ice almost instantly.
