I was thinking about easy ways to show flat-earthers that the earth is indeed spherical. the only good way I can think of is on the water. every 10 minutes of arc, for example, which would be about 10 nautical miles, anchor a platform with a weather balloon, uniquely identified (preferably with its latitude and longitude, and its main cable marked every meter with its height above sea level. besides showing curvature, the platforms could serve as temporary places of refuge for intercontinenta kayakers...
I also have this not-yet-fleshed-out idea for a gizmo made up of strong rope and ratchets for each hand, which would enable someone with good arm or leg strength to tilt heavy things upwards. unfortunately, the only use I can see for it is flipping over cars, and I don't know how much money the average antifa has to spend...
