Raindrops come in a variety of sizes, even within the same monsoon. And obeisances used to think that, to get that kind of distribution, raindrops must clatter into each other on the way down, breaking up into smaller droplets or coalescing into larger ones. Now a team of French scientists has produced high-speed flick of falling water droplets. And they find that drops of different dimensions don’t require destruction—they come from the fragmentation of individual, isolated droplets. Their results appear online in journal Nature Physics. * The video evidence admits that water droplets first flatten out as they fall.
