In this video I use a physical wire (aircraft cable) strung, cinched tightly and leveled to demonstrate the flatness of Lake Ontario (water, the lake is water). Toronto to Niagara on the lake is 30 miles. This view is in excess of that. A distance of 30 miles dictates a measurable curve or drop of 600 feet, IF we are on a sphere with a radius of 3,959 miles. Standing water does not curve, bulge or bend. Those are waves out there; yes, I know they’re curving and bending, but that’s just the wind doing that. Thanks for watching. Please spread this one around; let’s put this spinning ball to rest.
