Why Do Geese Fly In A "V"?

Here is another site from the government to make you richer in knowledge. Ask questions or view questions and their answers. The topics are: Agriculture, Astronomy, Biology, Botany, Chemistry, Geography, Home Economics, Meteorology, Vehicular, Physics, Inventions and Zoology.

It's not a huge site, but there are plenty here to learn from. It's just a fun site. There are some really good questions though. Here is one which I've never heard of, "Can you tell the temperature by listening to the chirping of a cricket?" How about "Why does hair turn gray?" and "Why do fingers and toes wrinkle in the bathtub?" I love this one: "Is it possible to fry an egg on the sidewalk if it's hot enough?"
