The wand movement is to the tap the top or surface of the target, with your wand, twice. So." He rapped the top of the lantern he had set down earlier, said the incantation out loud, and the lantern seemed to disappear. Jared cast Finite - verbally, for the benefit of the students - and the lantern re-appeared.
"Concentration and focus are more essential to this charm, than many others. The more you concentrate, the better your results. If your mind isn't on the charm, it's likely that half the target is going to disappear, and half remain in plain sight." No good, that.
"Go ahead and try it out on your lanterns. And," he added, before any of the students could start getting ideas. "No one is going to cast the Disillusionment Charm on themselves and then move away from their hay bale." They could cast it on themselves. If they remained on their hay bales until they nullified its effects. He wouldn't put it past some of the students to sneak off. "If anyone does so -" And he would know if someone did - "That's fifty points from their house and a week's worth of detention."
Luin sat on her hay bale, glad to be back out of the forest again. She had stayed pretty quiet during their time in the forest, not entirely comfortable with the darkness outside of the light of the lanterns. She then thought about the next charm, taking note of the warning given by the professor. She started to practice the charm on her lantern, clearing her mind and focusing on her task, "Disillusiona!" the lantern disappeared. She smiled and then reversed it, 'Finite!' the lantern appeared again. She smiled to herself and then looked around at the rest of the class.
