Subject: Why am I able to make a needle move by concentration on it?

Why am I able to make a needle move by concentration on it?
My experiment involves holding a needle hanging by a thread in my 
fingertips.( the thread is in my fingertips)
 If I concentrate that the needle should move in cirles it will.
If I concentrate that the needle should move in a north/south direction
it will.  What I want to know is why this happens. I think it has to do
with particles and wave energy.  Also I have hung the thread from a 
banana hook and the needle will move if my finger is on the top of the 
hook.
