How many balloons will it take to fly away?

Question

If i bought a bunch of helium balloons, can i fly away? how many to buy? What if they are in the winnnie the pooh shape?

I weight 140

Answer 1

depends on how much you weigh

Answer 2

When balloons fly away, they go up so high, they get turned inside out and become loonballs and they end up in a loony bin where all the loony people are kept. This is nice, since each loonie can then have a Loon Ball. Actually, air pressure gets weaker as the balloon goes up, and the air inside the balloon soon becomes stronger then the air outside, so it swells up and up until it bursts, then it falls back to earth, into someone's swimming pool.

Answer 3

in 1982 Larry Walters tied from 42 to 45 helium-filled balloons he bought from a local Army-Navy surplus store to a lawn chair in his backyard. He soared to 16,000 feet and drifted for several hours before shooting the balloons with a BB gun. When he landed his balloons became tangled in some power lines, though he was uninjured.

The balloons were 4 feet wide so that translates to roughly 1400 cubic feet of helium for 42 balloons.

Answer 4

It is basically a mass, vol & density calculation which can be established by matching your mass with the corresponding helium vol. Practically however other frictional & gravitational forces( for the large balloon) also come into play. It would as such be best to fill a ballon with one cu m of helium & tie different masses it it rises. Thereafter take that mass: body mass ratio & that will give u the vol of helium reqd. It would however be better to add atleast 15% extra vol of helium for other atmospheric drags.

Answer 5

How funny!You know I used to wonder about the same thing when I was a kid.There's a song that I was crazy for and still like alot about 99 red balloons go by and whenever I heard it I would think about flying away while holding onto 99 red balloons.So maybe 99 balloons would do the trick.Sure wouldn't hurt to give it a try.But can you imagine handing a balloon to your child and suddenly they start to go up up and away....?My son would just squeal with delight at that one.

Answer 6

Sheesh people, does NOBODY pay attention??? The Mythbusters needed about 4000 helium balloons (!!!!) and the kid only weighed thirty pounds. It was way more (like double) than the basic calculations said it would take.

Answer 7

i was whatching a porgrame about a person that straped 20 weather ballons to a deck chair and flew up a thousand fet this has acutally been seen by two pilots as well but the thing is that it would need a lot of helium

Answer 8

There was an episode of mythbusters about this. They used at least 100 helium balloons and the person didn't budge. I would guess at least 500. Did anybody else see that episode? My numbers might be a little off. At any rate, it is a LOT of freakin' balloons.

Answer 9

at sea level, one cubic foot of helium can lift 0.067 pounds. you would need at least 2090 one cubic foot balloons full of helium to lift 140 pounds.

then you would need more one cubic foot balloons to lift the weight of the balloons and string and achieve buoyancy.

Answer 10

that episode was the ****. and 200 is way off. it took 500 to lif t a 90 pound girl

Answer 11

1000 helium ballons
