The audio begins with the slight, anticipatory rustle of a plastic object being held above a glass of water. Suddenly, the object is released, and it descends swiftly through the air. The instant the object hits the surface, a distinct splash resonates, signifying the disruption of the water's calm surface. The plastic object plunges into the glass, causing a series of smaller, bubbly sounds as it displaces the water. The sound reverberates briefly before slowly fading away, leaving behind the subtle, continuous murmur of disturbed water settling back into stillness.
