    Cool PFP sir. Your face is magnetic, JK. It is due to friction instead. :)

    Yes, it's due to friction.

    Pretty cool stuff. Does that also depend on the size of pores, and perspiration amounts? If there is too much sweat, one might expect objects to slip off the face. If there are small pores, the face would probably be too smooth for metal to grip. Conversely, if the pores were too large, maybe the contact patch would be reduced?

    I have autism and think differently (old Apple motto apparently), so I ask a lot of questions.
