You can perform this trick while your legs are crossed, or while resting your knee on the edge of a table/desk. Hold the lighter from hinges-side of the lid with your index finger and thumb. stretch your index to make enough gap for the lighter to go through. make a quick move with hand to the side and the lighter will open and rotate 180 degrees between your thumb and index finger. Hit the bottom of the lighter against your knee, the wheel will stroke on palm of your hand between your thumb and index finger and ignite.
