The bubble gum bubble blowing tutorial is as follows:
Buy bubble gum (or chewing gum). If you've never bought bubble gum before, figure out what flavor you want to buy first. There are many flavors of bubble gum, including strawberry, orange, apple, apple, lemon, chocolate, and so on. You can choose your favorite flavor first and try others later. They are usually available in small stores. Some bubble gums don't blow very big and break easily, while others are so sticky that they stick to your face.
Put a piece of bubble gum in your mouth. Since you're just learning to blow bubbles, don't put too many pieces in your mouth at once. Chew it in your mouth and keep chewing until the bubble gum becomes soft and smooth and is no longer sweet before you can start blowing. This will take a few minutes, so you'll have to be patient. Don't chew it too long, though, or the bubblegum won't be as flexible and won't blow as well.
Use your tongue to knead the bubble gum into a ball, a process that involves using your palate and tongue. Use your tongue to move the bubble gum to the tip of your tongue, against your teeth, and then use your tongue to press the bubble gum into a disc. Continue to press your tongue against the disc until the bubblegum becomes a thin layer wrapped around the front part of your tongue. You'll want to do this process gently and slowly, and if your tongue accidentally pokes through the bubblegum, start over from the step of kneading it into a ball.
Withdraw your tongue from the center of the bubblegum layer and place it between your lips. Blow slowly inward, and you'll feel the air filling the bubble; keep blowing slowly. Some people blow their breath just out of their mouths instead of their lungs, and the air that comes out that way definitely won't last and the bubbles won't be as big as they could be. So remember to take a deep breath before blowing and blow out from your lungs only.
Keep blowing, the longer the better, until you burst the bubble. Practice, practice, and practice. You'll definitely fail more often than not at first, but failure is sometimes part of the fun experience. Keep trying until you succeed in blowing a bubble, then you'll feel accomplished. Practice in front of a mirror so you can see if the bubble gum is in the right place on your tongue. Also, you'd better practice indoors so that you won't be disturbed by the wind and sunlight outside.
The next goal is to blow bigger bubbles. Once you can blow bubbles with one piece of bubble gum, you can try blowing with multiple pieces so you can blow bigger bubbles. Chew on two to three pieces of bubble gum at a time until you run out of sweetness and it becomes soft and sticky when you start blowing. As before, turn the bubble gum into a thin layer that wraps around your tongue and blow a small bubble. Then slowly keep blowing into it until you think it's big enough.
