Jason DeFrain  asked the Naked Scientists:

I was discussing gravity and some basic physics with my 7yr old son and I thought of a rather interesting question.  I am no math wiz so calculating this on my own is a little more than difficult. =)

If we were to drill a hole all the way through the center of the Earth to the direct opposite side, what would the atmospheric pressure be at the center?  Assuming that the humidity was say 60% and the temperature was 80deg Fahrenheit.

Many thanks,

What do you think?
