Miri, honey - you are missing the point of the thread --
which is - proving the Earth to be spherical or flat -
only using experiments that "every-day" people could conduct on their own -
without simply trusting what NASA and other government-based organizations are putting forth.
All:
Do you think we could all possibly stay on topic?
Do you have any ideas of how the 'shape' of the Earth can actually be proven
to an individual
by an individual?
