 Welcome to the SNAP, the segment where we answer frequently asked questions in a very rapid fire format. So let's get right into it. What is the rocker? The rocker is a tactile feature designed to help more easily locate the airport. The rocker also serves the purpose of facilitating airport modulation, whether it be through the feathering or rocking, either to produce rapid pulses or steady consistent flow to cool and condition your vapor. For the first technique we're going to demonstrate how to feather using the rocker and the airport. So use the rocker to quickly find the airport and then take it up to your mouth and as you inhale you'll feather it like pushing a button rapidly. This is going to create rapid pulses, creating a different airflow dynamic that a lot of people prefer. Now the other technique, grab the airport and the rocker like you did before, rotate them in between your thumb and forefinger and you can partially obstruct or you can do it a little bit more rapidly. Open it up, completely cover or do it halfway. And now with practice you will learn how to accurately and easily adjust your air to vapor ratio on the fly. Thanks for watching the SNAP.
