While I agree that it is an interesting finding, the lede of "at room temperatures" buries the fact that using a median of 330-360 gigapascals as a measure of the earths' internal pressure equates to a pressure of 8223639745.0093 pounds per square foot. (Rough calculations based on 3,300,000 to 3,600,000 atm for the Earths' inner core)

[Edit to correct the maths] = 5325785739.6251 pounds per square foot.
