I am not telekinetic but i've learned how you can make people think your are telekinetic.
Unfortunately, I will not show you how to make things fly across the room, but I will explain how to move a pencil across a table by mind control.
First, you will need a pencil, an audience, and a table. Sit down, and move yourself close to the table. Place the pencil in front of you. With your finger draw an imaginary circle around the pencil, and then draw a line in the direction of where you want the pencil to move (this will distract your audience). Gently, and inconspicuously blow the pencil and it should move as you draw the imaginary line.
You may want to practice this.
