This experimentation is part of a reflection on the materialisation of invisible phenomena, particularly breath. Starting from a simple and universal gesture blowing into the neck of a bottle I sought to capture and extend this spontaneous sound. This gesture, at once playful and nostalgic, becomes here a starting point for designing an object that transforms breath into a sonic experience. The object acts as a mediator: it reveals an invisible energy by translating it into vibration and sound, while making musical production intuitive and accessible.
