The sphere is 6600 cubic meters, and its huge volume ensures enough lift. It can walk freely in a spacious space, and the pod can carry 29 people at a time.
Ascend to heaven, go through the clouds, turn on the phone? God's perspective? A 360-degree bird's eye view of Dujiangyan must be tense, exciting and full of happiness!
The romance of helium balloons lies in the unknown imagination.
We never know what will happen next or where we will land.
At least helium balloons can make us jump out of the mortal world and overlook the earth during a trip, and let us try to change the perspective and way of seeing the world. ?
At the moment when the helium balloon flies, we can temporarily put down our inherent obsession and hand ourselves over to the sky overhead, which has never been seen at close range and is infinitely close.
But at the same time, we should also know how to fear the sky. Even though human courage is great and the scientific survey on the ground is correct, there are always some unknown areas in the sky that we can't reach. As the old saying goes, there are unexpected clouds in the sky.
Don't give up the beauty of helium balloon travel because you choke on food, it is more worthy of vigilance. Don't blindly believe that with the existing technology, you can control unknown flights, even all kinds of negligence, and lack of awe of life and the sky. ?
Helium balloon Helium balloon is a kind of balloon filled with helium, which can not only keep the gas from leaking for a long time, but also bear the weight of children.
Suitable for many occasions, such as advertising, entertainment and so on. Helium is an inert gas, which is far safer than hydrogen and will not explode, but the cost is higher. Helium is widely used abroad. ?
Aluminum balloons are also called hydrogen balloons and helium balloons in China.
Some people call it aluminum foil balloon because there are different understandings of the material of aluminum film balloon, but the name of the material used in the balloon here should be called aluminum film more appropriately;
Some people call it a hydrogen balloon or a helium balloon because the gases filled are different. When inflating aluminum balloon, hydrogen is generally used in China. Because of the cost, it is generally called hydrogen balloon in China, but the disadvantage of using hydrogen is that it is more dangerous.
In foreign countries, helium is generally used to inflate aluminum balloons, so heliumballoon is generally written on the inquiry sheet.
Helium is a rare gas. The element name comes from Greek, which means? The sun? .
1868, someone observed the surface of the sun with a spectroscope and found a new yellow spectral line, which was regarded as an unknown element on the sun, hence the name helium.
Helium is a colorless and odorless gas under normal circumstances. Helium is the only substance that cannot be solidified at standard atmospheric pressure.
Helium is the most inactive element and basically does not form any compounds.
Helium is mainly used as protective gas, working fluid of gas-cooled nuclear reactor and ultra-low temperature refrigerant.
