What happens if someone drank liquid oxygen

VERY INTERESTING QUESTION.

You'd need immediate incubation and surgery in order to survive. The swallowed liquid would boil furiously and turn into high-pressure gas (in this case, oxygen). That gas would put too much pressure on your stomach and esophagus, perforating one or both of them. That would release the gas into your chest which would collapse your lungs. It may also perforate your diaphragm and traumatize your visceral organs, particularly your spleen and liver. You'd be in excruciating pain and unable to breathe on your own, and you might be bleeding to death.
