Gravity-defying mail jumpers of Lake Geneva, WI

Of course, readers would interpret the headline as hyperbole. They would not expect the article to be about a new technology that literally defies gravity. However, precisely because of the hyperbolic headline, readers would expect something more interesting than a hop that's maybe the size of two normal stair steps. This is very clearly deliberate deception.

When we say an elite high jumper or pole vaulter or gymnast is defying gravity, it's hyperbole. Here it's just nonsense.
