How to Sign "One Second"
To sign "one second," start by holding your non-dominant hand flat in front of you, with the fingers pointing up and the palm facing your dominant side. Form a "1" handshape with your dominant hand by extending your index finger. Place the palm-side of your dominant index finger against the palm of your non-dominant hand. Finally, pivot your dominant hand forward slightly at the wrist, mimicking the quick ticking motion of a clock's second hand.
