After the jokes of our chemistry teacher, the girls almost fainted.

Today, the chemistry teacher burned — put a container of liquid nitrogen on the lecture and let's pour everything around, and then break it with a hammer, they say, what a strong substance. He then pulled a large yellow glove over his hand and stuck one finger entirely in the flask with the potion. He assured that he did not feel any pain, and in general this experiment is safe ... almost.

After half a minute, he pulled out his finger, demonstratively showed it to the audience, and then with a happy look he swung at it with his hammer! The shrapnel spread throughout the audience. Impressive ladies assured, the guys fell into a stupor.

Only a minute later, he admitted that he had slipped a fake finger into the glove in advance. Joker, man.
