There's two celestial objects that hits you know.

Revelation 8:8
And the second angel sounded, and as it were a great mountain burning with fire was cast into the sea: and the third part of the sea became blood;
9And the third part of the creatures which were in the sea, and had life, died; and the third part of the ships were destroyed.
10And the third angel sounded, and there fell a great star from heaven, burning as it were a lamp, and it fell upon the third part of the rivers, and upon the fountains of waters;
11And the name of the star is called Wormwood: and the third part of the waters became wormwood; and many men died of the waters, because they were made bitter.

and there's hail stones as heavy as talents (20 kilos or so) falling down:
Revelation 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.

there's going to be alot of stoning.
