About This Puzzle
Did you know? A spherical soap bubble forms the shape it does because it is the least-area surface that can enclose a given volume of air. In 2000, mathematicians proved the "double bubble conjecture," establishing that two merged bubbles adopt the minimal possible combined surface area for enclosing two separate volumes. Source
