"Obviously we just needed a steeper cone angle, so we fabricated one at 75° but it still jammed. Perplexed, we increased the angle to 82.5°—practically a straight pipe—and it still jammed. Thus began our surprise introduction to the field of bulk material handling, where entire books have been written and companies have been founded solely to solve this issue known as ‘bridging’, and the frequently-associated ‘hammer rash’." This is hilarious I think partly because it's such a common theme in engineering or life in general. For some reason things that initially seem so benign and straight-forward end up becoming absolute rabbit-holes of startling complexity.
