Cameras Capture Falling Snowflakes in 3D reports that a gadget that can snap photos of individual snowflakes in freefall could lead to more accurate weather predictions.

Researchers at the University of Utah have developed the Multi Angle Snowflake Camera (MASC), which uses three high-speed cameras triggered by infrared sensors to shoot flakes as they float to the ground, with exposures as quick as 1/25000 of a second. The device also measures the flakes’ fall speed, all without touching them, which would disturb the measurements.
