Why an Entire Lake Disappeared Into a Salt Mine

In November 1980, a lake in Louisiana disappeared in about three hours. It didn't dry up and no dam failed. It went down a single hole about the width of a large pizza — and the hole made itself bigger as the water poured in. Lake Peigneur sat on top of a salt mine, held up by pillars of salt. When an oil rig drilled into the mine, fresh water met salt, and a small hole turned into a runaway drain. This video follows that one principle all the way down: why the hole kept growing, why the pillars gave way, how 55 miners got out alive, why a canal ran backwards, and why the same process is still used on purpose today.
