A curious incident occurred in a parking lot in Preston, Minnesota. The driver of the tanker truck climbed into the cab when the huge steel tank shrank in a second, like an aluminum can. The driver immediately ran away from the car, but nothing else happened. Most likely, when emptying the tank, air was not pumped inside. The resulting vacuum turned out to be stronger than the resistance of steel. The metal could not withstand the atmospheric pressure and shrank inward. Source: Lord Of War
