That is the same thing as a helium filled weather balloon. It seems only = half inflated at ground level , but the helium will expand as the = balloon rises to a level where the lift of the balloon equals its weight = (Archimedes' law) or even exploding it if the balloon was overinflated = at ground level. ------------------------------------------- MH '72 97 '77 96 '78 95 '79 96 http://go.to/saab96
