Helium can lift approximately 1 gram per liter. Thus, you need approximately 80000 liters of helium to lift said person, or in other words, it would require 80000 / 14 5714 balloons.

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.

Re: How much helium do one need to lift 1Kg You need about 700g of helium to generate 1kg lift (assuming the helium is at the same temperature and pressure as the surrounding air).

Therefore, 1m^3 of He will correspond to 1.2kg/m^3 minus the weight of the Helium, 0.17kg, which means that we roughly need 1m^3 for 1kg. 60 pound corresponds to 27kg, so we need 27m^3 of balloons.

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.

(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.

Helium And Nitrogen Helium’s molecular weight is only 4 while nitrogen’s is 28. Because of this, the interior of the helium-filled balloon is lighter than the air around it, so it floats. If our cartoon baby weighs about seven pounds, he or she would need over 200 one-foot balloons to even begin to lift off.

For Balloon (inflated) it says: You may transport this items in carry-on or checked baggage. For items you wish to carry on, you should check with the airline to ensure that the item will fit in the overhead bin or underneath the seat of the airplane.

VIDEO: Just Like In ‘Up’, House Floats Into Sky Under 300 Balloons : The Two-Way National Geographic Channel’s How Hard Can It Be? show decided to see if it could use balloons to float a whole house — just like in the Pixar movie Up. The answer: yes.

While no one can ever guarantee a weather balloon will soar to a specific height, the balloons typically reach between 60,000 and 105,000 feet. However, the highest recorded weather balloon flight on record was launched in 2002 and soared to an incredible height of 173,000 feet.

Legislation regulating the release of balloons Mass release of balloons is illegal in several states and cities, including Virginia. Jurisdictions that have laws in effect dealing with balloon releases include: Connecticut, Florida, Tennessee, New York, Texas, California and Virginia.

A bundle of helium balloons may have caused a private twin-engine plane to crash last year, killing the pilot, according to a recent report from federal investigators. The report from the National Transportation Safety Board said the pilot was flying too low, hit the free-floating balloons and lost control.

11” latex balloons generally last between 12-20 hours filled with helium, and about 2-3 days when treated with Hi-Float. Foil balloons last approx. 5-7 days. Air-filled balloons generally last for a couple of weeks, but will not float.

One is that atmospheric pressure is dramatically reduced at high altitudes, so a helium balloon expands as it rises and eventually explodes. If you inflate a balloon beyond its limits at room temperature, it will break into small pieces up to about ten centimetres long.

Although a helium balloon can rise to altitudes of five miles (8 kilometers) into Earth’s atmosphere, it’s got to come back down eventually, and when it does, it wreaks some havoc. That colorful little scrap of latex may end up living in the Great Pacific Garbage Patch.

A burst of helium balloons can actually harm people in a very bad way. After the span of five hours, leave some balloons to float to the ceiling, if these do not pop, it means that it is same to release more balloons, but in case they do pop, then give extra time and do the above test again.

Because they are soft and malleable, latex balloons easily conform to an animal’s stomach cavity or digestive tract and can cause obstruction, starvation and death. As a result, latex balloons are the deadliest form of marine debris for seabirds. They are 32 times more likely to kill than hard plastics when ingested.

Dangers Balloon Releases Pose to Birds Balloon releases impact all types of birds, from songbirds to birds of prey to seabirds, and the consequences they face coming into contact with balloons can be devastating.

The animal is usually killed from the balloon blocking its digestive tract, leaving them unable to take in any more nutrients. It slowly starves to death. The animals can also become entangled in the balloon and its ribbon making the animal unable to move or eat.

It is very dangerous to inhale nitrous oxide directly from the canister, and doing it in an enclosed space is also very dangerous. Never place a plastic bag over your head. If you take too much nitrous oxide you risk falling unconscious and/or suffocating from the lack of oxygen. People have died this way.

Inhaling nitrous oxide in a dangerous way will not cause any warning symptoms until the user suddenly becomes unconscious. Then brain damage, followed by death, can occur within minutes. These risks are unlikely with the common balloon method.

Ingesting even a small part may kill an animal. Ribbons and strings attached to balloons have strangled animals or cause loss of limb or deformity due to entanglement.
