How can only one cheek be inflated with air?

1.11K viewsBiologyOther

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.

You aren’t so much “pushing air from one cheek to the other” as you are just tensing the “full cheek” to force the air in it to the other, now not tensed, side
