Abstract
A bubble producing assembly has a frame having a handle section and an opening, a fan positioned inside the opening, and a bubble producing device positioned above the fan and extending over the opening. The bubble producing device has a primary loop having an enclosing edge that defines an interior opening, with the primary loop disposed at a first vertical level. The bubble producing device also includes a plurality of secondary loops disposed at a second vertical level that is different from the first vertical level, the secondary loops positioned with respect to the primary loop such that the secondary loops extend into the space defined by the interior opening. The secondary loop has a cylindrical wall extending vertically therefrom. The wall can have an angled configuration, with a circumference having a varying length. In a preferred embodiment, the secondary loops are smaller in size than the primary loop.
