There is a great video clip about an experiment with gum and helium. These guys are creating a balloon that can lift a person. Using the law of hydrostatics, the driving force must be at least equal (as can be seen in a certain part of the video) to the weight of the man with the balloon. Watch this how they fly in the air with the balloon.
