<p>This apparatus for ''Forming and Controlling Large-Volume Bubbles'' consists essentially of four elements: First, a bubble-forming loop (12) made of a flexible, large-pore (substantially noncapillary) material able to store large quantities of bubble solution by adhesion to a large surface area, by formation of numerous small reservoirs in the large pores, and by surface tension in the solution film enclosing the loop material, the film uniting with the solution stored within and able to release the solution quickly to an expanding bubble; second, a support (14) for supporting the bubble-forming loop; third, a control member (16) for controlling the opening and closing of the bubble-forming loop; and fourth, a solution reservoir (28) can be provided for maximizing the continuity of supply of solution to the bubble-forming loop. A drip cup (52) may also be provided on the bubble-forming loop to catch solution draining down from the loop.</p> |
