  • The Odd Air Bubbles

    The Odd Air Bubbles

    Though it looks like a strange underwater panorama, this image by photographer Marek Miś actually captures air bubbles trapped beneath the slip cover of a microscope slide smeared with drying callus remover. According to Miś, “Callus remover is one of my favourite agents for taking micrographs. It can create unusual crystalline forms. This time I found on the slide these interesting air bubbles before the callus remover started to crystallise.” I confess that I wouldn’t have thought to use callus remover for art!

    This image earned 3rd place in the Micro category of the Close-Up Photographer of the Year awards. See more winners here, and find more from Miś on the web and Instagram. (Image credit: M. Miś)

  • Microbubble Necklace

    Microbubble Necklace

    When a drop impacts a pool at very low velocity, a thin layer of air can be trapped between the drop and the pool.  When this air film ruptures, a ring of microbubbles forms and expands.  Multiple “bubble necklaces” can form if the film ruptures at several points.  These rings travel outward until the film is completely destroyed, leaving a chandelier-like shape of microbubbles.  See the phenomenon in action with one of the videos linked here.
