Visualization 4 | 21 vs 100 kHz video of complete injection event (70 ms). Related to Fig. 1

Visualization 5 | 21 vs 50500 kHz video of complete injection event (70 ms). Related to Fig. 2b

Visualization 6 | 21 kHz vs 10 MHz video of complete injection event (70 ms). Related to Fig. 2c

Visualization 7 | 75 vs 666 kHz video of complete injection event (70 ms). Related Fig. 4

Visualization 8 | Accelerometry of a 70 ms long injection event of water at 5 bar. The sequence is taken at a camera frame-rate of 75 kHz and an illumination rate of 333 kHz - i.e. accelerometry data is extracted at 75 kHz over the entire injection. Related to Fig. 3d
