The Earth in a bubble symmetry

With its perfect spherical shape and unperceivable interfaces, a soap bubble floating in the air was reflecting the whole universe around it. In the instant of the shot, its existence relied on the slight overpressure of its interior with respect to the external lukewarm air boundaries of a spring day at Parco Nord (Milano, Italy). This screen in tension was overlapping the Earth surface and the sky in a single image, merged along an evanescent equator containing the symmetry center of an imaginary spherical crystal. A moment after, the liquid barrier dissolved in a myriad of drops, switching off our perception of a dreamy surrounding.
