What If the Earth Were Hollow?

Man has dreamed of outer space travel for hundreds of years...but, what about inner-Earth travel? Could it work? Young scientists explore the notion of jumping into a hole through Earth and the factors that affect the journey, such as the Coriolis Effect. The narrator also discusses the differences in gravity, the magnetic field, and Earth's rotation at different points along the way.
