Flat Earth Vertical Canon Experiment

David Wardlaw Scott mentioned this experiment in his famous work Terra Firma. We have a mini version of it here by  JG24FanUK

Now I count the projectile’s journey to be 10 seconds. Seeing these boys maintain that they are in the UK, that means at their location, the Earth’s rotation is 600 mph.


Now how far has the earth rotated in the 10 second span? Well, let’s consult the mph/feet per second calculator:


Here we see that 600 mph is 880 feet per second.

10 seconds multiplied by 880 feet is 8, 800 feet. That’s over a mile and a half!  Yet the projectile lands right next to them as if the Earth isn’t moving at all.
