it took 53 12" helium balloons to lift a pound, you have to add the weight of the string and balloons
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.
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.
10000000 helium balloons
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
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
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.
The number of balloons needed to lift a person depends on their weight and the lifting capacity of the balloons. A standard party balloon can lift about 14 grams. For example, if a person weighs 70 kg (70,000 grams), it would take approximately 5,000 balloons to lift them, assuming ideal conditions and no additional factors like wind or drag.

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.
The number of balloons needed to lift a 10-year-old depends on their weight and the lifting capacity of the balloons. A standard helium-filled balloon can lift about 14 grams. Assuming the child weighs around 32 kg (approximately 70 pounds), it would take roughly 2,300 balloons to lift them off the ground. Factors like the size and type of the balloons can also affect this estimate.
depends on how large the balloon is! ;D
In the movie "Up," Mr. Carl Fredricksen's house was lifted by 20,622 balloons.
