Always spectacular to watch the magical billowing revealed by the schlieren imaging technique. As in the last investigation the images below are of dense cold water descending from an ice cube in room temperature water. While we dont normally see this magical cascade of water within water the schlieren imaging technique allows this ‘invisible’ phenomena to be seen. Schlieren uses a set of mirrors to control the light and make the invisible visible. Differences in water temperature/density cause the light to bend and dissrupt a uniform color gradient, which allows the intricate patterns to be photographed.
This is a followup to the last investigation. This time I used some small circular plates of ice, and some larger ones (you can see one held in the field of view). The field of view is approximately 4″ in diameter for these images.
