How many helium balloons does it take to lift a kilogram?

Answer 1

To lift about 110 pounds it could take any where from 100 to 150 balloons to lift a person, a lawn chair, food, and many gallons of water. A man by the name of Kent Couch from Oregon demestrated this for us by flying from his home all the way to Idaho. I would'NT try this unless you have a parachute of some kind of device to help you have a better landing. The Balloons could be about the average party balloons (large ones) that are about 11in in diameter. Now remember this is very dangerous and could even be lethal.I hope this helped you.Thanks for looking--Tiana5701
