Emmet/Rosalie> brick wall

He held up his right fist, twisting his fingers to reveal the snowball he'd saved in his palm. It had not melted there; he'd squeezed it into a lumpy block of ice. He had his eyes on jasper, but I saw the direction of his thoughts. So did Alice, of course. When he hurled the ice chunk at her, she flicked it away with a casual flutter of her fingers. The ice richocheted across the length of the cafeteria, too fast to be visible to human eyes, and shattered with a sharp crack against the brick wall. The brick cracked, too.
	The heads in that corner of the room all turned to stare at the pile of broken ice on the floor, and then swiveled to find the culprit. They didn't look farther than a few tables away. No one looked at us.
	"Very human, Emmett," Rosalie said scathingly." Why don't you punch through the wall while you're at it?"
	"It would look more impressive if you did it, gorgeous."
