False Lift

Is a horizontal flow of air over the crown of the balloon, assisting in the lifting of the balloon system. Exactly the same effect that when the rounded back part of a spoon is held freely downward from the fingers, against the vertical flow of water from out of the kitchen sink tap, the spoon is pulled into that flow of water.... Try it with a spoon!

Launching With False Lift

Balloon is Distorted
and at Low Volume
False Lift is Maximum

As the balloon Reaches the Speed of the Surronding Air the False Lift Compeltely Stops
