                            From lerpy: As well for the cooling, opening a tank wide open to get that icing then placing a beer bottle in front of it (full of course) is a great way to get a nice cold beer quick on a hot day. Making cold beer is not a waste of air.   I’m not so sure an $8 air fill is worth a cold beer :) I suppose it depends on how thirsty I am and how hot it is outside.
