The filming style of capturing the moment when natural flatulence occurs while a woman relaxes alone has been commonly used in previous fart-themed works. This production relied solely on this method, and we were surprised that all four women managed to pass gas naturally, especially considering many women usually avoid doing so even after eating or drinking. By creating a relaxed atmosphere—having them eat snacks, read magazines, and unwind—we were able to portray a more authentic and natural experience.
