This research continues from the Air Jet System research. I started to think about the process of the floating a ping pong ball on an airflow and how it could be used on a larger scale. This led me to Air Tunnels, which are used by skydivers to practice control while moving through the air. I discovered there is a place not far from my home where the public can use a wind tunnel. There are two forces at work, Gravity pulling the boy down and the airflow pushing him up. When the boy is stable the forces are balanced. It was good to research this method of floating first hand as it was something i have not seen before.
