Chris eyed the dungbombs in Professor Carlton's and her volunteers' hands wearily. He, being a Prefect for a few terms now had not had the best of luck with dungbombs. He had expereinced a few rogue students throwing them down a corridor. The smell was sickining.

He raised his wand and watched as Professor Carlton gave the call and the heads up to start their spells. "Viseo Ebullio!" the Head Boy shouted, he was sooooo ready to NOT smell that terrible stinch. He left his wand over his head as he felt and watched the bubble form over his head and then waited to see what would happen.
