Although hot air balloons may seem pretty straight forward, there are some if not many details about how they actually work that people are unaware of. This blog looks to enlighten and reiterate the facts of how these amazing hot air balloon rides take place and how they do what they do so well!
What Are They Made of?
There are three main components that make up one entire hot air balloon; the basket, the burner and the envelope.
The Envelope
This is the term used for the actual balloon of material that holds the air that lifts the entirety of the three components. Typically the material used for the envelope is nylon which is strengthened with sewn-in webbing. Nylon is light yet highly durable with a high melting temperature making it perfect for the use required of a hot air balloon.
The Basket
With the need for all components of a hot air balloon to be light in weight, the basket is usually made of wicker. As well as being light, it is highly durable whilst remaining flexible to help absorb shock for those sometimes bumpy landings.
The Burner
The burner is the terminal in which propane gas burns in order to heat the air within the envelope causing it to rise.
The Science
A hot air balloon ride is an exhilarating experience which happens via a very basic scientific principle: buoyancy. This is where warm air rises within cooler air. When the air is warmed, its mass is significantly reduced per unit of volume. For example, 2 cubic feet of air weighs around 56 grams. When that air is heated, it weighs 14 grams less. Thus per 2 cubic feet of air can lift 14 grams of weight. Although that is not very much, this is why hot air balloon envelopes are so huge!
Balloon flights have become sought after experiences and are readily available for everyone to try – why not test the science for yourself!
