Ice Bubbles

I noticed a plantpot saucer I had left outside had what appeared to be interesting thin ice crystals in the frozen water,

Just the subject for another session with the LCD microscope

This time I remembered that the pixel size for photographs needs setting every time the microscope is switched on.

On further thought these appear to be air bubbles frozen in the ice. The bubbles form as air which is dissolved in the water is released as the temperature drops and gets surrounded by frozen water.

    Ice is amazing stuff. I'll see if I can find some hair ice tomorrow.
    I wonder what caused all the little tube like things.

    I've found a couple of similar photos on the net. They appear to be air bubbles. The water releasing dissolved air as the temperature drops. The freezing process must have been fast enough to surround them.
