If you open a bottle of champagene, or fizzy beer, you get a fizz.
But it's controllable, - you just contain the excess spill-over with a napkins , or whatever.
But, if you drop a bottle of beer just before you open it, or take the cap off, - or iff you shake the bottle and then take the cork out, why, all hell breaks loose! Why?

It's a Physics conundrum I don't understand.

P1* V1 /T1 = P2*V2/T2, so why the heck does P3 (the pressure when opened) become uncontrolled?
