Press the pad of your thumb and the end of your middle finger together with some force. It helps to offset the finger to the left side of the thumb (looking down at the thumb). Hold your thumb still, and try to pull the tip of your middle finger down to your palm, until it overcomes friction and snaps against your palm at the base of your thumb.
