Peter's clone moved near the hole and threw two marbles at the same pace but one of them reached near the line while another stopped a little far from the line. He walked to the marble near the line and touches the exact place where the marble was, with his thumb.
Then, he spreads his other fingers. Then, he lifts his thumb and placed it where his middle finger reaches. Finally, he raises his other fingers and places the marble on his middle finger. He pulls the middle finger with his other hand fingers and shot the marble in front of him.
But, his shot was so accurate that it collided on the side of the marble and his own marble moved near the hole. After that, he repeats the same hand signs and shots the marble inside the hole.
