A rainbow is nothing more than scattered light from the sun. When it rains and the sun shines simultaniously the raindrops act like a prism, refracting the light so that a spectrum appears in the sky. In other words, a rainbow is an optical illusion which cannot be physically touched nor approached. Even if you could touch it I don't think you would be able to feel it since it is just light.
