Don't feel like an idiot, they are the same thing as the liquid out tube in a corny, they go down to the bottom of the keg and provide you with beer until the kegs dry. The cool thing about the sanke setup is it has both the gas and liquid setup so that it lets co2 in at the top and pushes the beer up the tube from the bottom.... Does that make sense?
