physics-shock

Just finished playing Bioshock on hard settings.  Very good game, even ending is nice and big boss fight is not overwhelming.  I think I will buy Bioshock 2 even though based on reviews it is not as good as the first one.
My humidifier is acting weird: it stuck and I cannot dissemble it to fill with more water.  I unplugged it, let it chill...instructions say: just lift the tank for water off the machine...it just won't lift...tried with a knife and screwdriver... not even a possibility in instructions...I'll try tomorrow...or I will break it.
