Looks like one of Pam Anderson’s implants...
Too smooth and symmetrical to be hail. During the Great Tribulation there will be deadly hailstones!
Rev 16:21 And there fell upon men a great hail out of heaven, every stone about the weight of a talent: and men blasphemed God because of the plague of the hail; for the plague thereof was exceeding great.
BTW: A talent (Latin: talentum) is an ancient unit of mass. It corresponded generally to the mass of water in the volume of an amphora, i.e. a one foot cube.
A cubit foot of water probably weighs close to 20 lbs.
