Okay... descending foam balls from the ceiling, into the bin. Not supposed to be a problem. The incantation and wand movement weren't a problem... Rory felt confident, a hundred percent sure of himself. After all, he was good at Charms.

He pointed his wand at one of the descending balls, "Depulso," he said, sweeping his wand. The Charm was successful, he managed to banish the ball - preventing it from falling. The only problem was his aim. The ball didn't fall into the expected bin, but instead it fell out one of the windows - How. Wonderful.

He smacked his wandless hand on his face. "Idiot," he thought to himself. He felt embarrassed, others already managed to place the balls in the bins, and he of course forgot to aim and through it out of the window.

He scratched his crooked nose, with his bony long finger. At least the balls weigh like feathers, and no one could get injured if the ball fell on him/her. Or even better, at least he didn't banish one of the younger students out of the windows - that could of been bad. Feeling slightly encouraged, he practice the wand movement once more. He was ready, and this time he'll aim accurately and succeed.
