How Much Does A Balloon Weigh? How Many Balloons Are Needed To Lift An Adult Flying To The Sky?

How Much Does A Balloon Weigh? In other words, this is the question that helps you determine how many balloons you can buy without giving up! 


Everyone must have seen the movie Up and remember to print its symbol: The house flies with the ball! It is one of the most popular works of 2009 with its unique details, meanings, and idols.

So what if I look at that film from a little scientific perspective? Does there exist a certain method that makes the whole house fly by balloons?
n fact, says Kevin Garry, a professor of aerodynamics at Cranfield University, "If you have enough helium, you can lift anything."

It is true and sounds very simple but there is 1 word IF is very big, it seems to be similar to the WORD word in the sentence: "Give me a fulcrum, I will lift the earth!" of the famous scientist Acsimet
Going back to the above problem, to lift a whole building to the sky with only a large shadow seems unrealistic, less feasible, so what if only to raise one person?

How many balloons are needed to lift an adult flying to the sky?


With the above question, it is easier to solve and much more practical than the house above! In the article How Helium Balloons Work people study and find that:

"Helium gas has a lifting force of 1 gram/liter. For example: If you have a ball that can hold 5 liters of Helium, it will lift a weight of 5 grams!".

A normal balloon at an amusement park can have a diameter of 30 cm (about 1 foot). So to determine how many liters of helium the ball contains, we have the equation: 4/3 x Pi x R x R x R. In which, R = Radius of a ball, in this case, it is equivalent :
30cm: 2 = 15cm
Therefore, we can calculate the volume of a 30cm diameter balloon as follows:
4/3 x Pi x 15 x 15 x 15 = 14.137cm blocks ~ 14 liters
Therefore, an ordinary amusement park ball can lift about 14 grams with the assumption that the weight of the balloon and rope is negligible.

If you weigh 50 kg (about 110 pounds) is equivalent to a weight of 50,000 grams. Dividing that number by 14 grams (weight of each lift ball) will produce the necessary number of balls of 3,571.42 ~ 3572.
In another case, if you choose a ball with a diameter of 3m, the number will greatly decrease. Using the same formula as above we have:
4/3 x pi x 150 x 150 x 150 = 14.137.000 cubic centimeters = 14,137 liters - equivalent to 14kg lift

Thus, only 4 balloons will be needed to make sure they can lift 1 person weighing 50kg off the ground.
If you want to raise the diameter of the ball to 30 meters (about 100 feet), it may not be necessary because, at that time, it will raise 14,000 kg and also the size of a large balloon.

The man flew up with balloons


In fact, at least 1 person tried this method. It was Danny Boria, in Calgary, Canada. According to Theguardian, Danny filled Helium into 120 balls of 6ft diameter. And that beam helped him fly for 20-30 minutes in a row!

Of course, to prepare for this project, Danny not only had to calculate his weight but also have to worry about the "weight" of an armchair.

On the day of the execution, everything began to follow the calculations of Danny and his colleagues. However, later, due to bad weather conditions, he was forced to land in an industrial park a few kilometers away.

Although the journey was much shorter than expected, Danny was still very happy because he and his colleagues were successful in their somewhat crazy project.
