I found this link from facebook posted by my one of the friend. This is about a girl(student) who caught while cheating in exam of Devi Ahilya University Indore. She drawn answers of two questions on her hands in form of MEHNDI design.
Even though the cheating is not a good practice but I’ll really appreciate her work.
What the F… fantastic diverging idea Sir jee.
She must have given at least 1-2 hours to draw MEHNDI on her hands and at least 3-4 hours to get it dry.
