How it works is... you tell it how many people you want to have at your party, and then you use the sliders to say how many people you want to get:
a) Tipsy
b) Buzzed
c) Drunk
d) Hammered
It then calculates how many kegs, cups, and how much ice you need.
Of course, it would be perfect if it told you how many Bucklers to bring to the event!
