5 Places On Earth Where Gravity Doesn't Seem To Exist
2. Hoover Dam (Clark County, Nevada)
Rather appropriately, the Colorado River's Hoover Dam seems to be enveloped in a vacuum. Watch any of the many videos of tourists pouring the contents of bottles over the edge of the 750-foot barrier, and you'll see them flabbergasted as it flows upwards. It must be holy - God dam.
Or perhaps not. If the dam really is fringed with an anti-gravity field, why doesn't it likewise send the wowed water-wasters' caps flying? Or the amazed onlookers themselves?
Time for a little myth-dam-busting. Gravity is perfectly accounted for along the perimeter of Black Canyon's massive bulwark; it's actually the shape - and height - of the structure which creates an updraft, blowing the spilled refreshment skywards. Still an amazing spectacle, but nothing remotely spooky.
