I thought bought 12 bottles of water at the supermarket last year.
In holland blue bottles are non sparkling, red bottles are sparkling so i bought bleu ones. Damn germans put sparkling water in bleu bottles.
Oh well, so we brushed our teeth and did the dishes and stuff like that with sparkling water.....
I don't really drink any water though, beer really tastes better.
And to keep the beer cold, use an inflatable boat or swimming pool and fill it with festival water.
And when you can't keep your beer cold anymore, drink whiskey, warm wiskey is not as bad as warm beer.
