@maija Learn how to blow bubble rings on the bottom of a pool if you have one. It's easier. Also if you can get a trumpet mouth piece and learn how to make it sound properly. That will help you with the water rings, which will help you with the smoke rings. It's about very sudden very short yet very steady bursts of pressure from the lips, smoke rings are different from water rings or a horn mouthpiece because they won't work with buzzing lips. Round mouth shape, huff out from the diaphragm, not too much but don't push out too much, that will give you a long traveller, just use your jaw, tongue and round mouth to push out smaller rings. Think of the smoke and air like a liquid, because it acts like a liquid.
