You can't touch a rainbow because it is not a physical object; it is an optical phenomenon created by the refraction, dispersion, and reflection of light in water droplets. When light passes through these droplets, it bends and separates into different colors, forming a circular arc. Since a rainbow is essentially a visual effect dependent on the observer's position and the light source, moving closer won't allow you to reach it. Thus, it exists only as a perception rather than a tangible entity.
