It is really easy its just scary til u do it! Just pick your spot and gently pinch but try to use more pressure on 1 side so it will wanna lean 1 way! U will feel the stem wall start getting soft to where as u pinch u can lean it over as u pinch it! Once it gets soft and starts to lean u can just push down on it like u saw a lil at a time til its laying at least at 90° angle! Once the stem gets soft to where u can lean it over its really hard to actually break it unless u try to force it over to much at once too soon!
