These are my impressions of the sequences that may take down the grain. I'm particularly interested in the fluid dynamics that might create these patterns. Keep in mind that air is a fluid.
My questions are:
1. How is the air moving? Is there a rotating or counter-rotating action?
2. What causes the upper nodes to bend at such regular angles?
3. Why do the lower nodes bulge on the same side of the stalk as the upper node outward bends?
4. Is some energy present that is softening the nodes? Is heat involved? Is there a buildup of electrons or ions as the wind passes over the grain?
5. Do the plants twist at the roots as they fall?
