There is no air tight barrier in between my two cheeks, so how am I controlling the air in my mouth and directing it to one specific cheek? The deflated cheek is still floppy, so it’s not like I’m tensing a muscle to stop it inflating.
Also works if I have a mouth full of water, and can also be directed to top and bottom lips.
Thank you.

Fill your mouth with as much air as possible, including your lungs. Keep sucking in air. Now try to move the air around – its much harder to onlynhave one cheek inflated.
When you only have one cheek inflated, you only have enough air in your mouth to either partly inflate both cheeks or inflate just one.
Now if you deflate your lungs and mouth by breathing out as much as you can, really eliminate as much air as you can – you’ll notice it’s difficult to inflate even just one cheek. You don’t have enough air.
