Abstract
This apparatus for "Forming and Conrolling Large-Volume Bubbles" consists essentially of four elements: First, a bubble-forming loop 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, said film uniting with the solution stored within and able to release the solution quickly to an expanding bubble; second, means of supporting said bubble-forming loop; third, means of controllably opening and closing the bubble-forming loop while minimizing reliance on inertial or centrifugal forces; and fourth, means of maximizing continuity of supply of solution to the bubble-forming loop. Soap bubbles up to eight feet across have been made with the apparatus.
