Sound, tools and proper observation. or we can use the forces of nature. for example: wind; there is a pencil in the table. IN not UNDER. Ok? As you have we won't use our physical body parts to move it. What you will do is blow on it though your mouth and it will move. Or bring out a handheld fan and fan it all the way but not too much because it will fall on the table. Requirements: sound:whooshing of the wind and the sound of a rolling pen. tools: fan and a pencil. proper observation: observe on where it will go and do not make it fall. and MOST IMPORTANTLY. FORCES OF NATURE: WIND.
