6+The fourth-graders of a regular high school were incredibly lucky. Or maybe you were unlucky, depending on how you look at it. Their teacher (and also the school principal) is a witch. No, she doesn’t fly on a broomstick or brew a potion from bats, but she can send you to visit saber-toothed tigers or trolls, enchant the door and show what’s going on inside a mobile phone. At first, fourth-graders are scared, and then they become terribly interested. Especially those of them who have learned to cast magic themselves.
