it 's magic and i did it before when i was little and i can do it again , speedy said so that blind singer snowball said so , too , the magic juice is in my mind - he bore down with all his force , all his effort of will ... and the ease with which they flipped was stupefying , as if a punch aimed at something which looked like granite hit a cleverly painted papier-mach shell instead , so that the blow you thought would break all your knuckles instead encountered no resistance at all .
