近日，一则关于‘俄男子喝液氮鸡尾酒导致胃部瞬间撑爆’的新闻引发广泛关注。然而，经核实，该事件存在严重夸大和误导成分。实际上，液氮在餐饮中确实被用于制作‘冒烟’效果的鸡尾酒或甜点，但正规操作下极其安全。液氮沸点为-196°C，接触常温环境会迅速气化为氮气。若有人直接吞咽未完全挥发的液氮，体内温度会使其急速膨胀（1升液氮可转化为约700升气体），可能造成胃部压力骤增，引发穿孔甚至破裂，危及生命。不过，目前并无可靠医学报告或权威媒体报道证实有俄罗斯男子因此‘胃部撑爆’死亡。专家强调，正规餐厅使用液氮时会确保其完全挥发后再供顾客食用。消费者应避免自行尝试含液氮的饮品，切勿吞咽仍在冒烟的液体。此事件更多是网络谣言对科学现象的误读与渲染，提醒公众理性看待猎奇新闻，重视科学常识与食品安全。
Recently, a sensational news story claiming that ‘a Russian man’s stomach exploded instantly after drinking a liquid nitrogen cocktail’ has drawn widespread attention. However, fact-checking reveals the report is greatly exaggerated and misleading. Liquid nitrogen is indeed used in culinary settings to create dramatic ‘smoking’ effects in cocktails or desserts, but it is safe when handled properly. With a boiling point of -196°C, liquid nitrogen rapidly vaporizes into nitrogen gas at room temperature. If swallowed before fully evaporating, the extreme cold and rapid expansion (1 liter of liquid nitrogen can expand into roughly 700 liters of gas) inside the body could cause a dangerous buildup of pressure in the stomach, potentially leading to perforation or rupture—a life-threatening condition. Nevertheless, there are no verified medical reports or credible news sources confirming that any Russian man actually died from such an incident. Experts stress that reputable establishments always allow liquid nitrogen to fully dissipate before serving food or drinks. Consumers should never attempt to consume items still visibly smoking with liquid nitrogen. This case appears to be more of an internet myth distorting scientific facts for sensationalism, reminding the public to approach viral stories critically and prioritize scientific literacy and food safety.
