This invention idea was driven from reduction of buying more funnels to find right size of bottle necks. Equipped with different size of outlets you need One funnel pour liquid, powder or grains into bottle. I designed 2 things onto funnel to improve pouring liquid to narrow bottle neck. First one is grooved on suffice of outlet to easily move air in narrow bottle neck. Last one is adding counterclockwise swirl/vortex on top of funnel to be impacted with the Earth rotation.
