Frozen Soap Bubble — Crystallisation Sequence
499.00 د.إ
A soap bubble freezing at minus 15 degrees Celsius — the crystallisation front advancing across the bubble surface in a dendritic frost pattern that preserves the spherical geometry until the moment of collapse.
Description
Soap bubble freezing photography requires precise temperature control — the ambient temperature must be cold enough to freeze the film within seconds but not so cold that the bubble collapses before the crystallisation pattern develops fully. This image was made outdoors at minus 15 degrees Celsius with a macro lens on a tripod, the bubble blown and the crystallisation front photographed as it advanced across the bubble surface over approximately 8 seconds. The image captures the moment when crystallisation has covered approximately 70 percent of the surface — the advancing frost front visible as a sharp line between the iridescent liquid film and the white crystalline region. Dendrites from multiple nucleation sites are visible within the crystallised region, their growth directions determined by the bubble’s curved surface and the temperature gradient. Shot at 1/500 second in diffuse daylight, the frozen bubble appears to glow
from within with its residual film iridescence.
