conversation between pen and a pencil
By hitting a metal slinky with a pen/pencil. If you have a metal slinky at home, hang it down your stairwell, so its falling to the ground. Then, take a pen or pencil (preferably a pencil - the metal part between the eraser and the actual pencil) and it the slinky lightly. You will hear a faint sound of the lightsaber.
