1. An apparatus for generating bubbles comprising:
a housing;
an air flow generator positioned in the housing and configured to generate an upward air stream through an air flow passageway;
a bubble generating assembly configured to rotate about a first axis, the bubble generating assembly comprising:
a body; and
a plurality of follower members pivotably coupled to the body about a second axis, each of the follower members extending along a linear axis;
a trough configured to hold bubble solution;
a cam wall that is radially aligned at least with the air flow passageway;
a channel that is fluidly coupled to the trough and positioned radially inward of the air flow passageway so that each of the plurality of follower members extends over the channel during at least a portion of the rotation of the bubble generating assembly about the first axis;
wherein as the bubble generating assembly rotates about the first axis, each of the follower members rides along the cam wall and transitions between: (1) a lowered position in which a portion of the follower member is positioned within the trough to load the portion of the follower member with bubble solution; and (2) a raised position in which the follower member is located on top of the cam wall and the portion of the follower member is aligned with the air flow passageway; and
wherein each of the follower members transitions from the raised position to the lowered position by rotating about the second axis and falling downwardly due to gravity.
