First of all, if you know what kind of the rubber of plastic, then google it or refer some optical handbook. If the refractive index of your tube is bigger than air, you can use a light source with a specific spread angle, for example laser, to illuminate inside the tube, as long as light do not come out of the tube, the angle is smaller than the critical angle.
