By the way, preliminary calculations show that the 3 foot dia. hole app. 7600 miles deep would contain roughly 381,000,000 cubic feet of water. I think.

Anyway, how many cubic feet of water are on the planet? What percentage would 381 million equal?

There is about [326 million cubic **miles**](http://ga.water.usgs.gov/edu/waterdistribution.html) of water on Earth, so your 381 cubic **feet** is only 0.00000000126% of the total. Assuming minimal density change, of course.
