  1. Glycerine has an index of refraction of ~1.47, standard bottle glass has an index of refraction of ~1.51. They’re both colorless and their indexes of refraction are close so light doesn’t bend very much when passing from glycerine to glass or glass to glycerine. For comparison, diamond an index of ~2.41 (that’s why diamonds are so sparkly) and water’s is ~1.33.
