Here's the
linky, for interested persons.
chran and Denver are both correct, kruse10; your test (that is, you holding a pin with a ball on it) does not control for mundane explanations.
For example, your breath could be moving the ball. Your fingers might be consciously or subconsciously imparting a spin to the needle, which gets the ball moving.
What you have to do is think of all of the things that could be happening (breath, heat, movement) and put controls in for them.
You may not have tried this yet, so it's important to play around with it (in essence, you're trying to find out what, if any, limits there are to your ability).
For example: try sticking the pin upright in a plank of wood, then putting the ball on the other end of the pin. Put this whole setup on the floor, then set up a frame that dangles thin paper strips all around the ball (but which still lets you see the ball sufficiently enough to concentrate on it).
Can you move the ball without the strips of paper moving?
If the strips of paper move, the more likely explanation is that your breath is moving the ball, see?
By putting the pin in the plank, we remove your fingers from the equation (we're trying to rule out the possibility that your fingers are twisting the pin and imparting spin to the ball). If you have to be in direct contact, try lightly resting a fingertip against the pin. Does the nature of the ball's motion change? Does it now rock back and forth instead of spinning? The likely explanation is, then, that your fingers are imparting motion to the ball.
But let's say that you set up this rig -- say, the paper strip rig -- and you can get the ball to spin without the paper strips moving (and that you can do this without touching the pin). Next experiment: try to rotate the ball in either direction. Can you get it to go clockwise, or counter-clockwise, upon demand? Once it is moving, can you stop it and reverse its motion? Can you stop it on demand?
Once you know the answers to all of these questions, you'll be able to design a pretty tight protocol -- one that rules out all of the mundane possibilities such as heat, air motion, and conscious/unconscious movement on your part -- leaving as the only likely explanation that you actually are telekenetic.
Please let us know how your experiments go, and welcome to the Forum! : )
