Why we need to ban helium balloons?

Balloons are a popular entertainment tool in everyday life. We can blow with our mouths. However, the air in the balloon was too thick, so the balloon could not fly into the sky.

Most of the balloons that can go up are filled with hydrogen or helium. In the early days, the United States liked to fill balloons with helium. Since the disaster of 1.4 million helium balloons, the United States and the world have banned and released helium balloons.

What the hell is going on? Gases are not harmful gases. What a disaster this will bring to the people of the world.

Large balloon festival

Do you know the dangers of releasing helium balloons? Each balloon costs only a dollar. All the proceeds were donated to poor families.

The charity announced a Guinness World Record challenge with the launch of a disposable balloon that will allow caring people in the United States to experience a historic moment.

Initially, organizers estimated they could sell 200 balloons. Not much, but enough to challenge the Guinness World Record for a balloon release; To their surprise, they raised 1.4 million yuan for charity just by selling balloons. The balloons were packed in large mesh bags and stacked three stories high.

Notably, the Cleveland charity balloon was filled with helium. The reason for this choice is also related to the decision of the United States military.

Helium is one of nature's most valuable natural gas, most of which is stored in the United States and used by the U.S. Department of Defense to operate airships and fill light bulbs. Although helium was called the "blood of industry" at the time, the United States had a low utilization rate of helium and immature technological resources.

At the time, helium was expensive to store and transport, even more expensive than the value it created. As the airship faded into history, the Defense Department began wondering what to do with a shipment of helium in storage.

It seems a shame to lose it straight away. The Cleveland charity wanted to hold a balloon charity meeting, so the two met and filled the balloons with helium as the main gas.

Since the Earth's atmosphere is 78 percent nitrogen and 21 percent oxygen, only hydrogen and helium in the periodic table are much lighter than the same volume of air, allowing balloons to soar into the sky.

That's why the early Berliners chose helium. After all, there are only two gases to choose from, and hydrogen is so strong that it accidentally burns up the airship; Helium, which is relatively stable, is more popular.

The same applies to leading sequence numbers. Throughout history, hydrogen balloon explosion accidents are common, which makes us realize that helium balloons are obviously relatively stable. With demand on one side and a market on the other, the unprecedented balloon race began.

Helium balloon disaster

When 1.4 million balloons took to the sky, it was like a mushroom cloud burning in the city, according to media reports. It's a visual feast. Thousands of spectators gathered underground. They celebrate having lived through history, but they don't know what disaster they've caused.

It didn't take long for the cheers to go wrong. As the weather was not so good that day, it rained in some areas. The moist air in the air keeps the balloons low, and millions of them hover about 300 meters in the air. The air was so full that some of the balloons were compressed and began to make their way toward the Cleveland airport.

It is estimated that the tower was filled with balloons at the time. Many civil planes had just taken off, and their engines were filled with large numbers of balloons. There was no way but to go down.

We heard that the plane was attacked by birds, forced to land, but completely destroyed by the balloon attack. Only in America could such a strange story happen.

Typically, balloons stay aloft for several hours after launch
