I don't think the numerousness of the lines in
the grating that is the key idea. I think the
_spacing_ between the lines is what makes it a
diffraction grating. Eight or ten lines is enough
to do a pretty good job (although not maximally
convenient to set up).

you don't have a Cornell demo. slide?
