Movie S3.

Crack healing in the HDA state of a 0.9 M NaK tartrate solution in a polycarbonate capillary during the phase transition of HDA to LDA state (a different sample from that of Movie S2). (A) Cracks induced in the sample. The sample is rotated by 360° at 110 K to show cracks induced inside. The frame rate used for recording is 7.5 fps and video playback speed is 15 fps. (B) The HDA sample is continuously recorded during warming from 110 to 150 K. Note that cracks heal completely during warming. The frame rate used for recording is 7.5 fps and video playback speed is 240 fps. (C) The sample after warming. The sample is rotated by 360° at 150 K.
