Students can demonstrate the method of stellar parallax for themselves that holding up a finger, and looking at it with one eye, and then the other, will make the finger appear to shift with respect to a distant background (such as the opposite classroom wall). Holding their finger closer will result in a larger shift; holding their finger farther away will result in a smaller shift. Thus the shift angle will be inversely correlated with the distance.
