The above item was a small piece of popcorn. The surface of the popcorn looks smooth, but in the areas where it was broken away, there is almost a paper-like hexagon bee hive structure. This could explain why popcorn feels so soft and airy.
Through this process, I learned how much difference in structure an object can have. The popcorn piece I provided appeared to be very homogeneous to the human eye, but upon closer inspection I found that different regions had different support structures. In some of the images above, you can see that some areas blend between a hex grid and a blobby cave. Next time I eat popcorn I’ll think of this variation in structure (and people will think I’m weird for doing so).
