"Arithmos revelio scindo." Olly started by pointing his wand at the box, and as he said the incantation he worked the spiral upward. By the time he was done, though, his hand was reaching way above his head. That was much higher than it was supposed to be. He was not surprised when nothing happened. So he tried again. "Arithmos revelio scindo." Again he started with the point, but this time he tried to move upward more slowly. It went pretty well and his wand hand ended up about eye level, but still nothing happened.

The wand movement was weird, and it seemed pretty unspecific. Why wasn't there a specific number of spirals he had to complete by the time he was finished? Wasn't magic usually pretty specific like that? Maybe that was one thing that made this spell a bit more complicated than others. Part of his problem was also probably that he was focusing too much on the wand movement instead of the spell. Spells needed a lot of focus, and that was often a problem he had with making them work. Olly tried again.

"Arithmos revelio scindo." This time he tried to let his arm do it's own thing without thinking about it too much. He let it do whatever felt most natural. His spiral ended close to his shoulder and the whole thing had felt a lot better than the others, but apparently not good enough. He still had not many any numbers appear. But how would the professor know which students had made which numbers appear anyway?
