If you want to become adept at blowing smoke rings so that you can show others at a get together or party, you are going to want to practice. Blowing smoke rings looks like a simple thing to do, but you will find that there are mechanics and techniques that you need to employ if you expect good results. With practice, they will become easier and almost second nature so that you don't have to think about them as you blow them.
Some people use cigarettes to blow the smoke rings, but cigars have tobacco that is packed more tightly allowing for thicker smoke and, thus, easier to blow rings. The tighter the tobacco is packed the better it will be. If you find that the cigars are not packed as tightly as you would want, you can always pack them further by tapping the end that you put in your mouth against the palm of your hand.
The first thing that you will want to do is to light the cigar, preferably using cigar lighters as this will ensure that you evenly light the entire tip of the cigar. You will then take a large drag from the cigar and take in as much smoke as is comfortable. You will hold this in the top front part of your throat. It may take you a little while for you to get used to this, as it is different from the normal manner in which you smoke.
With the smoke at the top of your throat, you next want to push your tongue down toward your bottom lip. Then, form your mouth into the shape of an "O", as though you were going to sing "ooh", and not "oh". Make sure that you keep the shape as wide as possible for when you start to push the smoke. Next, start pushing the smoke forward in short puffs and silently say "uh" with your mouth. When the smoke escapes from your mouth, you will find that it forms smoke rings.
As you can see, blowing smoke rings is not as simple as just blowing smoke through your mouth. It takes some practice and some time to get the technique down just right. When you have figured it out, you will find it can be a very impressive trick to show your friends when you are down at the local cigar bar or playing poker at the house.
