Question

What are some interesting facts about Helium Balloons?

Answer 1

If you are in a car and the car turns a corner, the balloon goes to the INSIDE of the curve. That means if the car goes right the balloon goes right, but you lean left. That is because the heavier air goes to the outside and the lighter helium floats on air.

Even if the balloon is intact it will still go flat. Helium atoms are so small they will go between the molecules of most containers. Balloons are made of aluminized mylar because that combination leaks the least. 

BTW the same is true of oxygen and zipper storage bags. That's why they are made in three weights. Sandwich bags only need to hold up for one day so they are thin. Storage bags are thicker, and freezer bags are thickest to keep oxygen out for weeks or months.

Answer 2

Some of the facts are :

You would need around 6,000 balloons to lift you into the air if you weigh 75kgs. 

If you place a helium balloon inside a car and accelerate, it will move to the front of the car.

Helium is around 7x lighter than air.

Answer 3

^{Helium balloons are the lightest and most buoyant type of balloon. They can stay up in the air for a much longer time than other types of balloons.}

Answer 4

Helium balloons are the world's oldest balloons still in use, first used in the early 1800s. The Helium balloons were created by a group of American scientists in 1892. They were using balloons as a way to communicate and send messages, as well as testing new technology that was being developed at the time.

Answer 5

Helium has the lowest boiling point of all elements—4.2 degrees Kelvin (that -268.8 Celsius)—just 4 degrees above absolute zero. Helium is the only element that cannot be solidified by sufficient cooling at normal atmospheric pressure. Helium was the first element not to be discovered on earth.

Answer 6

1. Helium is a lighter-than-air gas, which allows balloons filled with it to float.

2. Helium balloons have been used for scientific research, weather forecasting, and as decorations at parties.

3. Helium is a finite resource and is obtained through natural gas extraction.

4. Inhaling helium can temporarily change the pitch of a person's voice, creating a comical effect.

5. Helium-filled balloons can reach altitudes of up to 30 kilometers (19 miles) before they burst.
