I am not a rocket scientist, just a retired engineer, but I am confused about 6 G = 60 psi. Do you mean 6 times the weight of the liquid, which would be less than 60 psi, or 6 times atmospheric pressure, which would be 90 psi)? Or something else? Or is that why rockets often do not perform well?

@Joe Palen - your confusion is understandable since the author made two mistakes, not one. Champagne is pressurized at 80psi on average (some as high as 100psi), which is 6 atmospheres (not 6 G). Actually the author made yet another mistake, because big rig truck tires can be inflated anywhere from 30 to 100psi, depending on the type of tire, the load and expected road conditions. American journalists are virtually never hired based on either knowledge or academic achievements. Now couple that with the 2009 PISA study of global educational standards, where the United States was ranked #25 out of 28 nations at the high school graduate level of study, and it is no surprise that you find such glaring mistakes in an article that is intended to be informative. It would be funny if it weren't for what this said about the future of America.
