14.7 should be enough to collapse all the air molecules at sea level.
The vaccum expert, and I mean expert should be along shortly to tell you
the whole story.

If that was true, there would not be any air here.
Check out Boyle's law


Get out 14.7 at sea level, should not be any gas in package. Take that
package to 33' below and if all the air was in it, would be 1/2 size, but
you have almost all the air out except for 1 pound, you are not going to
get 1/2 size.

When you are talking 7000 PSI you are going to find out the coffee
itself is pretty porous.
It is a shame that we are on the shallow coast or I would run out to
100' of water or more and drop this thing over, tied to a concrete
block and pull it back up, just to see what it does.
I like science ;-)

I suppose I could make a pressure chamber with PVC pipe and try it
that way. Maybe bury it in the yard first in case it blows up but if
it was full of water before I start, there really wouldn't be much air
in there to "blow".
