Air pollution is a big problem in the world today.  As a rain droplet falls it collides with airborne pollution particles and cleans the air.  In this video we show the microscopic, high-speed interactions of rain droplets with pollution particles.  By doing so we reveal the mechanisms by which rain cleans pollution out of the air.
