Colder drinks... Through low atmospheric pressure!

Everyone knows that the higher your altitude (and thus the lower your pressure), the boiling point of water drops (Which is why you can't get a decent cup of tea on an airplane, but I digress).

Anyway, the idea is that you build a bar with an airtight seal around the building, so you can use a giant vacuum pump to reduce the air pressure inside, thus reducing the freezing temperature of water, and allowing drinks at -10°C!

Due to freezing point depression alcoholic solutions can already be cooled well below 0C. Even so I must ask why this is a good idea: After you got over the vestibular issues and nausea you are not likely to want an alcoholic drink cold or otherwise. Airplane cabins are pressurized.

The freezer where I keep my vodka goes down to -18°C - why would I want to go somewhere else to drink warm vodka?

Per Wikipedia "Unlike the boiling point, the melting point is relatively insensitive to pressure because the solid/liquid transition represents only a small change in volume", so how low would the pressure have to be and could human's survive in your bar? Would I get the bends when I walked in? For these reasons, I'm going to have to bone. (-) When I need a beer, I don't want to wait.

It is time for you to go over your PT graphs. And don't sell any fizzy drinks...

>reduce the air pressure inside

That would be the bar-ometric pressure, surely?
