26 fluid ounces or 78 centilitres of Smirnoff Vodka (Preferably Smirnoff Black Label Vodka)
Soda (Preferably from a Seven-Eleven soda fountain)

Pour the vodka in a one gallon jug, then run to the Seven-Eleven down the street and fill it with a mix of whatever soda they have on tap. Put the lid on the jug and shake well. Serve chilled and over ice into punch cups.
