Helium Facts and Fun
 
Have some fun with floating Helium Balloons

What is Helium?

Helium is a chemical element. Take a look at a periodic table. It is located at the top right corner on the chart. Helium is a gas, it is a Noble Gas and it is non—toxic, colourless, tasteless and odourless.

 

The chemical symbol for Helium is He with an atomic number 2.

 

Helium is the second most abundant element in the universe. It is not the most abundant or accessible property on our planet Earth.

 

What is Helium gas used for?

Helium gas is very useful and important to us. It is used in many ways but lots of fun for inflating party balloons.

 

Helium gas is used to inflate blimps, party balloons and even scientific balloons.

 

It has many other uses. Did you know Helium is used in automotive Airbags? They contain a mixture of Helium and Argon gas.

 

Why is helium used in party balloons?

Helium gas is used to inflate party balloons as Helium is lighter than air. This is why party balloons can float away up into the sky above.

 

Where can you purchase Helium from?

Most party shops, florists and supermarkets can inflate all sorts of party balloons for you or you can purchase disposable helium cylinder or helium canister to supply helium to your party balloons yourself.

 

Why does helium float up into the sky?

Helium gas is lighter than air which so a filled party balloon will rise up into the sky, then be carried away with the wind and eventually disappear.

 

What happens to the flying balloon?

The air pressure around the balloon will reduce as it rises and the balloon will expand. Some balloons will burst (if they are filled completely up with Helium) and some balloons will deflate slowly over time (if they are not completely filled with Helium). The remains of the material will descend back and land on Earth.

 

Notes:

Inhaling too much helium can cause asphyxiation .

Descended pieces can be very harmful to our environment.
