Goodness, Thornton was nervous. Wand in hand, he looked down at his bag and got a flutter in his stomach. Not yet ready to chance it, he quickly scurried over and pulled out a smaller bag from within it.

Carefully extracting his quills (he always carried at least two!) and inks (so maybe he liked to color-code his notes), he set them aside against the wall, so that the small bag sat by itself, empty on the corridor floor.

Biting his lip, he looked at the professor and nodded, whispering the incantation under his breath. His palms felt sweaty and his wand felt awkward in his hand.

"Small tap. From the wrist." He repeated the instructions with his eyes closed, before finally approaching the bag. Was he meant to actually tap the bag or just mimic it. Rather than ask, Thornton dropped to his knees next to the bag.

The movement he could do. Small wrist movements were important with string instruments.. Ok, Thornton, enough stalling.

"Magnus Centrum," he said, timidly and with some hesitation, with a small tap on the edge of the bag. Thornton looked at the bag expectantly. It still looked the same, but from what Professor Flamsteed had said, it would, but for the inner dimensions. Hastily, Thornton thrust his hand into the bag to see how deep it went and...

promptly smashed his hand into the floor.

"Ow."

Well, that hadn't worked.
