Could I Dig a Hole Through the Earth?

The video explores the layers of the Earth, comparing them to an egg. It starts with the crust, the thinnest and most brittle layer, then moves to the mantle, which is hotter and made of melted rock. Beneath the mantle is the outer core, a liquid layer, and finally, the inner core, which is solid due to immense pressure. The video concludes by discussing the deepest hole ever dug and why it's impossible to dig through the Earth.
