Part 6/7:
Upon transitioning to granite samples, they encountered unexpected results. Out of the 13 granite specimens crushed, only two instances yielded visible bubble formations in the detectors. Notably, these occurrences coincided with crushing pressures nearing 70,000 pounds. The formations appeared clustered, which did not align with the expected random distribution of neutron bubbles, suggesting possible contamination from shock effects.
In one instance, a detector was dislodged, causing it to break and leading to an overwhelming number of indistinguishable shock bubbles. Despite this setback, the surviving detector continued to operate for the remainder of the experiment.
