Supplementary Movie 1

This file shows a high-speed movie of the break up of a granular stream. The camera falls with the stream to capture the break up of a stream of d = (107 plusminus 19) m diameter glass grains falling out of a D0 = 4.0 mm nozzle. The nozzle and reservoir of grains are housed in a 2.5 m tall acrylic tube, which is sealed and evacuated to 0.03 kPa (gas mean free path ~ 200 m) to reduce air drag.

Supplementary Movie 2

This file shows a high-speed movie of a stream of d = (130 plusminus 30) m diameter copper grains. Conditions are otherwise identical to those in Supplementary Movie 1.
