In 2025, optics experiments successfully trapped laser beams inside water droplets, creating a light show tiny yet mighty, visible only through precision instruments. In these intriguing experiments, scientists used the natural properties of water to confine light. By meticulously adjusting the angle and intensity of laser beams directed at tiny droplets of water, they achieved total internal reflection within the droplets. This phenomenon occurs when light hits a boundary at a certain angle, tr
