“So we were quite happy that the limpet teeth exceeded that. “One of my colleagues on the paper, from Italy, found some exotic spider silk that was about 4.5GPa, and we measured about 5GPa.” This measurement is about the same as the pressure needed to turn carbon into diamond beneath the Earth’s crust.
