Lawson, moved around the students desks watching as they practiced their wand movements and nodded his head with approval. Some of course were better than others but he guessed he would get to see how good they were in about thirty seconds.

Moving back over to his desk and stood beside the cage. "Okay, I think everyone has had enough time to practice their wand movements now." He pulled the cover off the cage with a flourish and grinned at the students. "Doxy's" he said rather grandly, "Also known as biting fairies. I am going to open the cage in just a moment and release them into the class. I suggest you get yourselves ready because they're going to be flying straight at you." Marcus moved his hand down to the cage door and rested his hand on the latch.

"I want you to use the 'Impediment Jinx' to slow the doxy's down and if you concentrate hard enough you should be able to immobilise them enough to get them back into the cage. If anyone is unfortunate enough to be bitten by one, I have the antidote in my drawer."

He took a few moments to make sure that everyone was ready to go and then he opened the cage door. "Okay get to work" he called out as the doxy's flew out of the cage and headed straight for the students.
