5. Make your own potpourri
Counteract the smelly effects of too many possibly sweaty people, too many spilled drinks, and that one jerk who smoked in your bathroom by making your own potpourri. Just throw some fruit (lemons, apples, oranges will all work) in a slow cooker, and then add bay leaves, cloves and cinnamon. Unlike store-bought stuff, this won't make your apartment smell like a doctor's office.
