And besides the "reinventing the wheel argument" I would simply point out that there have been innumerable easy-to-reproduce experiments proprosed by RE'rs here, while the general counterargument is "too expensive." Why not make this thread a place for Flat Earther's to post their experiments that can be easily reproduced, are descriptively stated, and can be subject to peer review?
