ScienceDaily (Apr. 1, 2010) — Some 13,000 years ago the Earth was struck by thousands of Tunguska-sized cometary fragments over the course of an hour, leading to a dramatic cooling of the planet, according to astronomer Professor Bill Napier of the Cardiff University Astrobiology Centre.

How does a straw get driven through a fence post during a tornado?

Fence post... I don't know... but trees, that's easy. When a high wind blows the tree cracks develop on the windward side. A piece of straw gets blown into the crack. When the wind stops, the tree goes back upright, the cracks disappear, and the straw is stuck.

Since a fence post is not likely to bend like a tree, no doubt the straw gets blown into a hole that's already there.


But you didn't really want to know, did you. cool smiley
