Over at Science-Based Life, Kyle Hill explores the mystery of the lady who was impossible to lift. It's reminiscent of Lulu Hurst (the "magnetic lady" or "Georgia Magnet" and Annie Abbott ( "The Little Georgia Magnet"), both of whom traveled the world in the late 19th century amazing audiences because big powerful men couldn't lift them. Hill explains the secret, which comes down to basic physics:
[T]here are two reasons why the bodybuilders couldn’t lift the woman. First, as she moves her body further away during the second attempt, she is effectively tripling her weight. For example, if she is six inches away from the lifter’s shoulders in the first attempt and a foot and a half away in the second, the rotational force needed to lift her up goes from 56 foot-pounds to 168 foot-pounds.

Hey, remember that meteor that exploded over Russia last week? Want to know what it sounded like? Well, technically you can't because it's in infrasound, but the Comprehensive Test Ban Treaty Organization (TBTO) has released audio in which the data has been modified (sonified) so we can hear it:
