One quick point - this isn't a stupid question, I know that the main function of a water cooler is to provide cold water. However the water cooler where I work also provides boiling hot water for tea, etc. The hot water comes out of the machine as the same speed as the ice cold water; yet it's actually boiling (with visible steam coming off it). How does the mechanism inside the machine work, to provide this function so quickly and efficiently? I can't find anything useful related to this on Wikipedia - so any genuine answers would be very much appreciated; thanks in advance '_'

Its all gas - and lighter than air gas....so do you become heavier from releasing that light gas, or lighter (this is without follow through of course...)
