Psi-Wheel
This is a simple experiment to exercise telekinesis.
Take a metal thumbtack (the kind with a flat, circular base) and set it so that the sharp end is pointing upward. Now take a small square of white paper, about 1/4 inch by 1/4 inch (maybe even smaller), and carefully balance it on top of the tack. You can replace the bit of paper with a piece of carefully cut aluminum foil if you feel more comfortable with metallic energies.
Meditate for half an hour.
Now sit in front of the "psi-wheel" you have just created. Stare on one corner of the square of paper. Focus all your energy on that one corner, willing the paper to start turning on top of the point. Imagine the wheel (the paper) begins to spin on the axis (the tack). Hold your concentration for as long as it takes for you to get it spinning.
Once you have the hang of this, try knocking the paper off the tack!
