You will need roughly five thousand balloons to fly. It’s quite a lot, isn’t it? If, however, you chose balloons that are 12 feet in diameter, you would only need three of them to lift you up!
When balloons are released into the air, it may create a beautiful memory or photo, but it could be fatal for an animal. Wilson cautions, “What goes up, must come down,” adding, “Helium balloons, especially Mylar balloons, can travel a long way, kilometers even.
(Most houses weigh between 80,000 and 160,000 pounds.) Given that 1 cubic foot of helium can lift 0.067 pounds, it would take 1,492,537 cubic feet of helium to lift the house—or about as much as would be contained in 105,854 balloons, each 3 feet in diameter.
Additional Considerations. If you find out that your cat weighs 2000 grams, for instance, and that a single balloon can lift 4 grams, then you can calculate that you will require 500 balloons to lift your cat into the air.
For a baby, you would need fewer than 4,000 balloons. It would only take four of those to give you the same lift. One balloon that is 30 meters (about 100 feet) in diameter displaces 14,137,000 liters, so it can lift 14,000 kilograms (about 31,000 pounds) – this is roughly the size of a large blimp.
In order to lift 100 pounds (which would include the weight of your load, the balloon, and the helium) you would need 1449 cubic feet of helium. This would require a balloon with about a 15.5 foot diameter.

All parts of a rubber or latex balloon can be dangerous to dogs, even if they’re made of biodegradable material. It’s best to always keep them out of reach at all costs. From talking with my vet, he says that most foreign objects will pass through your dog’s system inside 10 to 24 hours.
Balloons are not safe for dogs; they can scare them if they pop, and they present a number of risks if chewed and swallowed. Choking, chemical poisoning and blockage are all potential issues that they can cause.
The reason dogs like balloons is the opposite to why some won’t love them; it’s all down to the way balloons behave, feel, and sound during play. Almost like prey, they can then catch and kill a balloon – this is great for dogs with this type of personality. Handy Hint: Some dogs are bred to have high prey drive.
They’ve got a volume in 14.1 cubic feet, so you’d need 105,854 of them filled with helium to lift the house. Eyeballing the cluster of balloons above the house in Up, let’s say on average, it’s 40 balloons across and deep and 70 balloons tall. Do the math and there could be 112,000 balloons in there.
How much does a hot air balloon cost. The cost of a commercial hot air balloon is around $92,000 – $105,000. That cost could balloon to $130,000 to $155,000 depending on the type of fabric, design, basket complexity, and burner model. Most commercial hot air balloons carry 6-20 people.
In fiscal year (FY) 2019, the price for crude helium to Government users was $3.10 per cubic meter ($86.00 per thousand cubic feet) and to nongovernment users was $4.29 per cubic meter ($119.00 per thousand cubic feet).
No, only balloons inflated with helium will float.
The balloon can only rise up until the atmosphere surrounding it has the same weight as the helium in the balloon. This happens at about a height of 20 miles (32 kilometers) above Earth’s surface. So, this is as far as a helium balloon can rise.
Toy balloons burst at around 10km, while professional meteorological balloons reach heights of 30km. The ultimate limit is set by Archimedes’s Principle, which says balloons will stop rising once their density matches the surrounding air. So there’s no chance of balloons entering the vacuum of space.
Foil balloons: $1.99 to $15.99, depending on size. Latex balloons: $0.99 to $1.29.
Under the same conditions, air has a density of 1.293 kg/m3. This means that at sea level on a 0ºC day, hydrogen provides enough buoyancy to lift 1.2031 kg per cubic meter, while helium can only lift 1.1145 kg per cubic meter of gas. Hydrogen, then, provides about 8% more gross lift than helium does.
A standard balloon is 11 inches. To lift just one pound, you would need 37 balloons and 423 liters of helium! The average human weight is 137 pounds. For that, you would need over 5,000 standard balloons and almost 58,000 liters of helium!
balloons that are released into the air don’t just go away, they either get snagged on something such as tree branches or electrical wires, deflate and make their way back down, or rise until they pop and fall back to Earth where they can create a lot of problems.
As you have just learned, the lifting force of helium is approximately one gram per liter. It doesn’t seem like much, that’s why you will need a lot of balloons to start flying!
The difference is what a litre of helium should lift: 1.11g. So 1000 litres lifts a little over a kilogram, and a 70kg human needs around 70,000 litres: very roughly 10,000 normal balloons, or approximately 300 of those party balloon cylinders at supermarkets.
It would take 4,800 balloons to lift a person weighing 60 kilograms (132 pounds) off the ground. Balloons are often part of our fondest recollections from childhood.
