[00:00:00]In 1986, a calm lake in Cameroon became a weapon of mass destruction. A limnic eruption at the bottom of Lake Nyos released over 100,000 tons of compressed carbon dioxide. The gas, heavier [music] than air, poured down the mountain like a silent invisible river at 60 miles per hour. As the villagers slept, the dense cloud suffocated all the oxygen in its path. 1,700 people died without ever waking up, enveloped by the relentless physics of a lethal invisible ocean.
