Poltergeists, or noisy ghosts, are believed by many to move objects and in this video you will see what appears to be compelling evidence that invisible entities are interacting with physical matter. The idea that one should provoke discarnate spirits is one that I personally would disagree with, they may not be amused. It is my opinion that one should avoid tempting spirits to prove that they are present, be very careful what you wish for is my motto.
