1. A cap comprising:
an elongated body defining a first channel extending from a first opening in a base portion of the elongated body through a neck portion of the elongated body to a second opening in a tip portion of the elongated body;
a side body defining a second channel extending from the first channel near the neck portion of the elongated body to a third opening at a distal end of the side body,
wherein the cap has only three openings and defines:
a first longitudinal axis through a center of the first opening in the base portion, a second longitudinal axis through the tip portion, and a third longitudinal axis through the side body,
wherein, when in a common plane, the first longitudinal axis forms a first acute angle with the second longitudinal axis and the second longitudinal axis forms a second acute angle with the third longitudinal axis and the first longitudinal axis forms a third acute angle with the third longitudinal axis, wherein the third acute angle is larger than the second acute angle, and
wherein the base portion is adapted to couple to a container;
wherein relative diameters of the first channel and the second channel are adapted to permit liquid to flow from the base portion to the tip portion under the influence of gravity while at the same time permitting air to flow into the first channel from the second channel.
