How to inflate a helium balloon?

1. The steps of helium balloon inflation are as follows:

1. Open the helium valve, put on the balloon nozzle, and lift the gas nozzle upward for inflation.

2. Close the valve immediately after filling the balloon to the required size.

Pull the tail of the balloon, and remember to pinch the air hole at this time, otherwise the balloon will leak.

Tie the tail of the balloon with a ribbon, and the balloon will fly after it is released.

Second, how can a balloon fly without hydrogen?

In order to make the balloon fly, the following conditions must be met: the sum of the mass of the balloon plus the mass of the air inside the balloon is less than the mass of the air. There are two common gases that can meet this condition:

Hydrogen and helium. If there is no hydrogen, you can only use helium. Helium is a colorless and odorless rare gas, which is less dense than air, stable in chemical properties, non-combustible and non-combustion-supporting, and very safe. Helium has special canned products in the market.

3. What is a helium balloon?

Aluminum balloon is also called aluminum foil balloon, hydrogen balloon and helium balloon in China, and its English name is foil ballo or mylarballoohelium balloon.

According to different occasions, it can be divided into birthday party balloons, toy cartoon aluminum film balloons, gift balloons, decorative balloons, advertising balloons, Valentine's Day balloons, Children's Day balloons, Christmas balloons, Spring Festival hydrogen balloons and other holiday balloons.

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 helium balloons are generally written on the query table.
