Uhhh....cotton balls. This wasn't supposed to happen, was it?

Nope.

"Finite!" Sophie said, ending the spell she'd attempted to cast before. The cotton balls stopped raining down on her, and the cloud was back to its normal condition before she'd casted. So she needed to cast again. Right.

She pointed her wand upward and made a counter-clockwise swirl with her wand. "Stiricidium Nubila!" she said. She tried her best to focus on what she intended this spell to do. No cotton balls this time. Nope. She waited to see what would happen. Pause. Then--something did happen. It wasn't cotton balls, no.

"Rocks?!" she said to herself. She covered her head and moved to get out of the way.
