i was not assuming the bottom of the paper stayed in place afterwards that would be miraculous. but the fact that it stayed flat just for a moment after the sword went through made me think the angle and direction of forces must play into it. obviously his perfect trajectory and geometry of approach are the main factors of his success, but each piece of the puzzle we can figure out by observing is worth investigating. i have to give it a try !
