The number of helium balloons needed to lift a person will depend on the person's weight. On average, it takes about 3-5 large helium balloons to lift 1 pound. For example, to lift a 150-pound person, you would need roughly 450-750 balloons. It is important to consider factors like air currents and ceiling height when attempting to lift objects with helium balloons indoors.
depends on how large the balloon is! ;D
It would take approximately 480 helium balloons to lift a 20-pound frozen turkey. Helium can lift about 0.04 lbs per balloon, so 20 lbs divided by 0.04 lbs per balloon equals 500 balloons.
It would take thousands of balloons to lift up the average house, as houses are heavy and balloons can only lift a small amount of weight. The exact number of balloons required would depend on the size and weight of the house, but it would be an impractical and unsafe way to try to lift a house.
It takes about 300 balloons to lift 200 pound manballoon filled with exactly 1 sq ft of helium yields about 28.2g (upward thrust)453.6 grams/Lb453.6(1Lb) /28.2= about 16 blnsSo to get one pound off of the ground it would take about 16 balloons16x200= 3200it would take 3200 balloons to lift a 200 lb person....Only hoover not continually rise on account of the uneven weight distribution and the temp differences in each balloon helium isn't as buoyant when cold, unless the temp is consistant. Wind is a factor; as well as the amount of static charge in the air
10000000 helium balloons
it took 53 12" helium balloons to lift a pound, you have to add the weight of the string and balloons

The average helium balloon can lift about 14-16 grams, or approximately 0.03-0.04 pounds. To lift 30 pounds, you would need around 750-1000 average helium balloons.
The number of balloons needed to lift a child would depend on the weight of the child and the size of the balloons. On average, it may take around 80-100 helium-filled balloons to lift a small child off the ground. It's important to consider safety measures and proper balloon handling if attempting such a stunt.
assuming that temperature is constant and that we're talking about regular party balloons (a "regular" 2-gram party balloon can hold ~ 16 grams of gas), you would need 6,156 baloons to hold your weight in equilibrium. you would need an amount greater than this to actually lift you (the more extra balloons, the faster the lift), and this is not accounting for the weight of the string. extrapolated from: http://malaysia.answers.yahoo.com/question/index?qid=1005123102737
25 Balloons (Approx.)(I might be wrong as I am not sure)
258 helium filled balloons filled to 34 psi each
