    Based on what I recall of the explanation by the person who figured it out: spinning makes fluid near the edge spin faster than fluid near the middle. The difference in speed creates a wave. Since it’s finite and moving, the wave interferes with itself and because of math, makes a hexagon. Something about how the wave pattern changes density and brings different glasses to the surface on the planets.
    Then they showed an example by spinning a bucket, and it kinda fell flat because they had to explain that a bucket isn’t a sphere so you have to spin it just right to get it to work, but it did work in the end.
