When light refracts from two different substances with the same index of refraction, the materials cannot be distinguished from one another. Since glass and glycerin have the same refractive index, a glass object in glycerin is invisible. This is actually demonstrated in this eerie video: The large beaker is filled with glycerin or oil, a Pyrex glass rod is lowered in the beaker. It is indeed invisible! Amazing science!
