There is a glass flask - on the bottom is blue food colored water. above it is oil. a glass stick (used for mixing) is put into it.. why does it seem invisible in the oil?

The index of refraction of the glass and oil are the same. Light goes through both as if it is the same material. with no light bending, the rod seems invisible. This is one way to test glass with different additives to Si O2 (quartz, silica)

If you are asking why the glass stick seems invisible, I think that it may be the way that the oil displaces light or it may be the angle that you were looking at. Sorry if this doesn't answer your question.

Its got something to do with the refractive index of the oil. Its has to be smaller for oil than for water.
