Tell me genius, how much vacuum would it take to collapse a mug made of, oh maybe 29 GA. SS? LMFAO.I never said "complete vacuum". I said they are sealed under vacuum, which they are, and if you puncture one (that is still under vacuum), you'll hear it taking in air to equalize the pressure. What about the thermal dynamics do you want to discuss?
I have played with this many times, pulled vacuums on vessels just to watch them implode. Try a propane tank some day, pull 29-30" of vacuum on one and hit it with a 30-06. Tannerite is cheaper but my way is much more fun.
