Many videos about this on YouTube , usually some guy tap a beer on a counter and it freezes before your eyes . I believe the reason has to do with the bubbles created when the bottle is shaken causing the contents to crystallize.

That is interesting because if I put a bottle of water in my freezer it will freeze and I know my freezer is not -20 C. My question is why did it not freeze until shaken?
The fluid in the bottle is just above the frezing point. When the gasses held in the solution begin coming out of the solution because of the change in external pressure (the cap was removed) and agitation (tipping or hitting the bottle) the thermal transfer that happens drops the temperature of the fluid...... and voila!!!! your beer freezes when it is opened.
You can do the same with a can of soda pop..... it's fluid in the can, but as soon as you open the top and the internal pressure changes...... the gas bubbles start escaping from the solution..... freezing your pop in the can.
It's all about how cold you like your beer.

Living in North Dakota I've had many experiences with freezing fingers, toes, soda, beer, cars, pipes, fuel etc. but had never witnessed the quick freeze.
Since the temp was -4F or -20C I took a 16 oz bottle of water out of the fridge and set it out on the front stoop.
I checked on it after a little more than an hour and the top half of the bottle was already frozen, shaking did nothing.
I'm still a skeptic.
