I don't think I have the patience to try to see if a pen can stick to the wall, but in class we did stick a balloon to the wall. It wouldn't stick after rubbing it on cloth, but did stick with hair. I vaguely recall it was because hair let go of electrons more easily...? I stuck a bunch of balloons to the ceiling after they stopped flying by rubbing them on my shirt though. Is it because the balloons were lighter? Because maybe the rubber material was different?

So..eventually the electrons will just have too hard a time moving into an object or out of one and that's what decides the limit?

...if I had a cloth and was using it to stick helium balloons to a wall, would the cloth get less and less effective?
