That's how I understand it. Maybe you could tie a some really big helium filled balloons to the corners of the table? According to that how stuff works page, a 3' diameter balloon will lift about .9 lbs, so 4 of those, in addition to the helium filled table, should get you off the ground. If in doubt, find a 6' balloon. They'll lift about 7 lbs.okay 1/2lb of dry weight is what the inside of the table will actually lift. so if the table weighs 3 lbs it will take 6x the amount of helium. i think i am reading right.
