Mrs. Weasley assumes the correct position and waits for Professor Rae to throw a bean bag at her. Out of the blue the professor throws it. Mrs. Weasley shouts Impedimenta and the bag immediately slows down. Cool! Then quickly she say Finite Incantatem and just avoids getting hit by the bean bag. She takes the bag back to Professor Rae's desk. That was a little too close for comfort, she says. I think I need a little more practice.
