Pressurized Air
It is usually not fun if you are hit by pressurized air right smack in the face, but this girl, or at least her sister, appears to be enjoying it. We do not exactly know what was happening here, but the father is blowing air into the girl’s mouth, perhaps as a sort of punishment or, on the flip side, their version of having fun.
We are banking on the latter as it would not be a fun way to discipline a child. We do give credit to the other girl for seeing the fun in this.
