It's sad because it's a relatively simple feat. Hold the first stick like you would a pencil, except without your index finger just above base joint of your thumb. Keep your middle finger almost alongside the stick and point it outward. Make sure your thumb is pointed slightly outward, too.
When you've got that right, put a stick so that it rests almost on top of the top joint of your thumb and under the last joint of your index finger. Moving your index finger up and down should also cause the stick to move in turn.
I'd make a guide with pictures, but I need a camera.
Hopefully that should work.
