xxx: The group I studied in was nicknamed the disaster group.

One day, a prisma disappeared from the lab. It is made of optical glass and is quite healthy. Who needs it, you ask? It turned out to be very simple: one madmuazel did a lab about determining the fracturing factor, counting 2.41. I looked at the sign – a finger! and diamond. Life succeeded" decided the girl, put the sample in the bag and ran out. Neither the weight of the sample (a half pound) nor the shape of the fence (a triangular prisma) brought doubt into the soul of the billionaire. Since then, there has been a saying: "The best friends of the fool is the K8 optical glass."
