Starting from helicopter, once the devil stick is spinning evenly remove the left handstick, and tap the devilstick in its center with the right hand stick. Tap the devilstick each time it becomes parallel with your body, and give it an upwards push. When the devilstick starts to lose momentum, resume helicopter. I will not go into great detail of the various static tricks since I don't use many of them myself. I will only mention the tricks that I do use, such as flips and handstick flips.
Static flips are pretty simple, but take a little bit of practice to get looking good.
Starting with the devil stick resting on the handsticks the DS is tossed into the air, does a half flip, and lands horizontally on the handsticks again. To make this trick slightly more interesting, the DS can be caught on crossed arms, and of course the devilstick can be flipped in either direction, and can do one or more whole rotations before being caught. This is the same as a static flip, except that as well as the DS being tossed into the air, one of the handsticks is as well. Thus you have the DS spinning parallel to the body, and the handstick spinning perpendicular to the body. It is also possible to flip the left handstick when the DS is flipped from the right hand.
