2-2.5 oz of rum
1/2 can of red bull energy drink (or Energy Drink)
Make sure the rum is freezing cold. I leave the bottle in the freezer over night. Fill a tall shot glass (2-2.5 oz) with freezing cold 10 Cane rum.\r
Pour 1/2 a can of Red Bull energy drink into a collins glass, drop the shot glass filled with rum into the collins glass, and drink it down!\r
