Do it more than 10 times if you can, try it like this: Take a breath in. Hold your lips shut. Make as many pops with your tongue until no more pressure can be in ur mouth. Breathe out very slowly. If it doesnt work, breathe more slowly, or maybe not as slow
The smoke? Yeah, like someone already said, when you do it more, its more obvious, also, try breathing out slower
not very learnable kinda born wit it i think make an airpocket on the roof of yyour mouth and slap your tongue off of it
