7. My favorite Flat-Earth "experiment:"

Thousands of years ago, some Greek scientists did an experiment using lighthouse beams to not only show the roundness of the Earth but also to calculate its approximate circumference with astounding accuracy, given the simple technology they had available. There is this one little modern Flat-Earth group of "scientists" who purported to use an updated version of this experiment to "prove" the exact opposite. I especially love the little sequence in which one modern "scientist" talks via a cell phone connection to another "scientist" and says, "Lift your light higher. The beam is not landing where it should land."
