Six girls (Ira, Vika, Lilia, Tanya, Veronica, Sasha) aged 18 were walking down the school corridor to the classroom where they had a physics lesson.
The girls walked and talked to each other.
A few minutes later, the girls reached the classroom, saw it was open, and decided to go in. Seeing a flask of something on a desk, they approached it. Vika took the flask; the other girls said it was better not to take it.
Suddenly, they heard a noise. Vika accidentally dropped the flask on the floor, and the office filled with white smoke. A few seconds later, all six girls lost consciousness, and then woke up in an office reminiscent of the Soviet era.
