When I lower on object towards my palm (e.g. a pendulum on a long string, or a small metal object, etc) I feel a very subtle, but distinct sensation on the palm of my hand. What could be causing this? I don't think it is heat from the other hand. Can an stationary object produce a subtle force/pressure on the air? Please note, you have to be very aware to notice this sensation. If you are closed minded, or have insensitive hands you won't notice it.
