Today we have a teacher at the lecture. He brought a vessel with liquid nitrogen for a pair. He licked them various objects, and then broke them with a hammer. He then wore a rubber glove and dropped his thumb into nitrogen. At the same time, he said that the pain is not felt at all and it is almost safe. He kept his finger in the nitrogen for 30 seconds and raised his hand. He touched his finger and said with a happy face that he was frozen.
He put his hand on the table and swallowed his finger!! There were pink pieces on all sides. The girls whispered, and the guys sat with this face of O_o. It turned out that he blinded his finger from plasticine and put it in a gloves in advance:))))))))
