Does air pressure affect the cup?

Question

I ride in 4 passenger planes (Civil air patrol). Does the air pressure affect the cup? I know on commercial airplanes the pressure is more controlled, but I think it might be different for smaller planes. Idk I feel like this is a stupid question but better safe than sorry

Answer

I’ve flown a few times with a cup in and saw no difference at all. From my experience, air pressure did not effect the cup.

Answer

Nope, not at the presures that you may experience 
You can even deep sea dive or go to space and do a space walk with a cup.

Answer

Hmm idk. I used one in a training single engine Cessna 172 but I never went above 4500 ft
