Pinch the end of one toothpick end between your thumb and index finger. Use either hand. Practice with each to see if you can accomplish the flick better with one over the other.
Apply pressure to the underside of the toothpick with your middle finger nail of the same hand.
Start a discussion by asking if anyone can explain how static electricity works. Keep the lingo simple, but make sure you add your explanation of how the toothpicks transfers static electricity because they're wood.
Rub the second toothpick on your sleeve, or any other fabric of good static electricity conducting capabilities. Balance the second toothpick so it is hanging half off the palm of your other hand.
Place the toothpick set up in your first hand under the second one, and act like you are waiting for the electrostatic to take effect.
Flick the bottom, or first, toothpick with the middle fingernail you have pressed up against it. The second toothpick seems to jump in the air, and fly away.
