blocks snowballs

The noise from the children stopped, dropping to furtive whispers, and I winked at Charity. She glanced from the children to me, amusement evident in her face. Not five seconds later Molly shouted, "Now!" and multiple snowballs came zipping toward me.
I lifted my left hand, focusing my will, my magic, and drew it into the shape of a broad, flat disk in front of me. It wasn't a good enough shield to stop bullets, or even well-thrown baseballs, but for snowballs it was just fine. They shattered to powder on my shield, revealing it in little flashes of pale blue light as a circular plane of force centered on the outspread fingers of my extended left hand.
The children laughed as they cried out their disapproval. I shouted, "Hah!" and lifted a triumphant fist.
Then Charity, standing behind me, dumped a double handful of snow down the neck of my coat.
