First off, your saliva has to be the right consistency. FOr me it doesnt work all of the time. It cant be too watery or it will pop as soon as you try. Move your tongue in front of your front teeth and it will create a small bubble on your tongue. Then once your tongue has the bubble on it, stick it out of your mouth and blow softly on the bottom of the bubble and it will float away into the air. It will take you some time to get it down, but thats the gist of it. Hope this helps.
