The cola bottle keeps fizzing because it contains carbon dioxide gas that is released when the bottle is opened. This gas is dissolved in the liquid under pressure, and when the pressure is released, the gas forms bubbles, creating the fizzing effect. Additionally, the presence of carbonation in the cola also contributes to the fizzing as the gas continues to be released from the liquid over time. **

The Sodastream may not be fizzing properly due to a few reasons. Firstly, the CO2 canister may be empty or not properly connected, so check to ensure it is securely attached and has gas remaining. Additionally, the carbonation level may be set too low, so try increasing the carbonation level to see if that improves the fizz. Lastly, the bottle may not be properly sealed or may be too warm, so make sure the bottle is tightly sealed and try chilling it before carbonating. **

The new Sodastream may not be fizzing properly due to a few reasons. It could be that the carbonation cylinder is not properly installed or is empty, so it's not releasing enough carbon dioxide into the water. Another possibility is that the water being used is too warm, as carbonation dissolves better in cold water. Additionally, the carbonation level may not be set high enough, so adjusting the carbonation level may help improve the fizziness. **

If orange juice is fizzing, it likely means that it has started to ferment and has turned into alcohol. It is not safe to drink orange juice that is fizzing, as it may have become contaminated with harmful bacteria or mold during the fermentation process. It is best to discard the fizzing orange juice and opt for a fresh, non-fizzy bottle instead. **

It is difficult to determine if something is a fashion trend without more specific information about what is being referred to. Fashion trends can vary widely and can be influenced by a variety of factors such as popular culture, social media, and celebrity endorsements. Without more context, it is challenging to definitively say whether something is a fashion trend or not. **
