How Long Would It Take to Fall Through the Earth?

What would happen if you drilled a hole straight through the Earth and jumped in? Vine decodes the journey: the crust, mantle, liquid outer core and solid inner core; why the planet has layers; the 12 km Kola Superdeep Borehole; how earthquakes revealed the core; Earth's magnetic field and its pole flips; why the centre is as hot as the Sun's surface; why gravity gets stronger before it fades to zero; the 38-minute fall; what air resistance and Earth's spin would do; where you'd come out; and the gravity train.
