North and South America have a surface area of about 42.55 million sq km or 4.58x10^14 sq ft (1 foot deep water is obviously 4.58x10^14 cubic feet).
Lake Superior has a volume of 12,100 cubic km or 4.2x10^14 cubic feet.
That's unbelievable!

It struggles with the more esoteric aquifers, and doesn't understand "North and South America" as an object, but still pretty cool.
So take the area of the lake and multiply it by 483, and now it is not surprising that you can cover North+South America with it.

To skip ahead, the Great Artesian Basin, the largest artesian basin in the world, would be just over 5 feet.
