What is Fizz?

The term 'Fizz' is quite generic and doesn't represent a specific technology on its own. It commonly refers to a bubbly or effervescent quality, often associated with carbonated drinks or chemical reactions that produce gas. Therefore, without further context, it's difficult to describe it as a technology. To provide a more accurate description, I would need more information about the specific 'Fizz' technology you are interested in. It could potentially relate to food science (carbonation), materials science (gas-releasing agents), or even software development (as a fictional name).
