Hanging a spoon on the face Well, I have seen many comical acts where people balance a spoon (or a fork) on different parts of the face like on the tip of the nose, forehead etc.
The do this by blowing moist air (see below) and immediately putting it on the face  

  

So i wanted to know is what is the force that temporarily binds the skin to the fork. I doubt it's friction or Van Der Walls force.
Can someone please clarify this for me? Is it some sort of chemical bond?  



Some addition
Also another method of doing this was to rub the concave part of the spoon on the tip of the nose. This article states how to do it properly. In the 2nd point it states  


  Eventually you will feel a slight tendency for the spoon to resist on the downstroke.  


What is this resisting tendency?
I would say the answer on this website is pretty near perfect.

To summarize, you need 2 things:


Enough friction between your nose and the spoon
The center of mass of the spoon should be on a line vertically downwards THROUGH the tip of your nose as illustrated in this image from the same website:




The friction is highest if both your skin and the spoon are free of greasy `lubricants'. Breathing on the spoon will add more friction by depositing a very thin (only a few atomic layers) film of water which, on this scale, behaves solid-like due to ordering effects as shown in this paper.
