A device to add or enlarge vents to disposable drinking cup lids. The vents are created by a portion on one of the utensils' ends. The portion has one or more markings to describe the diameter of the vent that will be made when the portion is passed through a disposable cup lid. The vents that are produced from using the device allow the cup's beverage flow rate to be increased and the beverage to be consumed more quickly and quietly. |
