- First, the lightest ball is placed on the vertical part of the ASTRA and then blown into the horizontal part over its own mouthpiece - as far as the generated airflow is sufficient, the ball is brought into a hovering position over the vertical part - now one can move from the lighter to the heavier balls
- The basket can be used to store the balls as well as a catch basket when blowing a ball upwards, if it is put over the vertical part of the ASTRA.
