How do helium balloons work? Are they safe?

If you see a balloon floating in the sky or in a shopping mall, it is probably a helium balloon.

Do you know how helium balloons work?

Helium is lighter than gas, so the inside of a helium balloon is filled with helium, which makes the overall density of the balloon less than the density of the surrounding atmosphere. This creates buoyancy, causing the balloon to float in the air. The outer layer of a helium balloon is usually a tough rubber or plastic material, which is effective against air pressure and keeps the balloon stable during flight.

Helium balloons have a wide range of applications. In the field of entertainment, helium balloons can be used for celebrations and party decorations. In the field of advertising, helium balloons can be used as a highly effective advertising communication tool, such as hanging helium balloons over airports or business districts to demonstrate products or services to potential customers. In the field of meteorology, helium balloons can be used for meteorological observations such as measuring wind speed, air pressure and temperature.

Is Helium safe?

Helium is odorless, tasteless, colorless, non-combustible, and an inactive gas. It is normally safe to use, but make sure to use them safely by following manufacturers’ instructions.

Store helium cylinders indoors in a safe place with good airflow, and keep them away from children, products like salt, or other things that can catch fire. Keep the helium cylinders upright when using, don’t drag a helium cylinder over the ground.
