How Deep Could You Dig By Hand? 🤨

Have you ever wondered how deep you could actually dig by hand? Well, let's start with the deepest hole humanity has ever dug. It is the Kola Superdeep Borehole in Russia, which reached 12 kilometers by using advanced drilling machines - yet its diameter is just 23 centimeters. The deepest hole where humans have actually been is the Mponeng gold mine in South Africa—4 kilometers down. It takes a one-hour elevator ride just to reach the bottom. But the deepest hole ever dug by hand is the Woodingdean Well in the UK — 390 meters deep, completed in four years. That's as tall as the Empire State Building, straight down. But how deep could you dig alone with just a shovel? Well realistically, you'd probably max out around 2-3 meters without wall support. At 1.25 meters, the walls can start collapsing—a cubic meter of soil weighs a ton and could crush you instantly. #digging #sciencefacts #technology #historyfacts #educational #learnwithshorts #learn
