Five meters
18 years ago
According to some old information I graphed, a woman weighing between 165 and 185 lbs would need to be inflated to over 5 meters (~ 16 to 17 feet) in diameter with helium in order for there to be enough lift from the helium to get her off the ground. Fortunately, on the inside of imagination, the laws of physics are a lot more ... stretchable.
