Hi,
I forgot a water-filled balloon in my backyard last fall. When my kid brought the frozen balloon in and removed the rubber, we were surprised to see the beautiful structure inside the ball of glass. I remember that glass paperweights used to have similar designs inside them. I used to think that air bubbles were blown into the glass to create the structure. But it looks like it is a natural phenomenon. I think even ice cubes in the fridge also have a similar structure.
Can someone please explain me or point to a resource that explains why this triangle structure, with air bubbles trapped at the center, is formed? Why don't we get uniform transparent ice?
Thanks.
