Figure 2.03. Supercooled water crystallizing. Click on the image to see a video of supercooled water crystallizing in an ice-cube tray when touched by an implement. This video is by Sandshoe on Wikimedia Commons. Other supercooled water videos can be viewed at these links:
Supercooled water 1,
Supercooled water 2,
Supercooled water 3. In each case, ice crystals grow very rapidly when the supercooled liquid is disturbed in some way.
