  • Description:
    A field of bubbles expressed from lung alveoli of mice was restrained in water under a flat surface. The bubbles were expanded by reducing the ambient pressure, then compressed by increasing this pressure to one atmosphere. Compression resulted in rapid, reciprocal changes in polar and equatorial diameters of the bubbles. Moving pictures of the process were taken. Measurements, from the pictures, of polar and equatorial diameters showed: (1) the size of the bubbles did not necessarily diminish after a series of compressions, (2) the shapes of the bubbles might have been determined by forces contributed by a variably mobile structure in addition to forces of surface tension and gravity. The suggestion is made that the rapid oscillation of the bubble diameters, as described, was produced by Thomson-Marangoni effects. [Description provided by NIOSH]
