Fizzy drinks are full of sugars and sweeteners. All of these things erode your braces. I recommend drinking it through a straw unless you know that you can properly clean your teeth a little while after:)
The fizz in the drinks are from carbon dioxide.
Carbon dioxide is what makes drinks fizzy.
Not all fizzy drinks are bottled in plastic.
Yes, you may take medication with fizzy drinks.
Yes Fizzy drinks carry more sugar compare to sport drinks.
The dissolved CO2 in fizzy drinks is bitter. Sugar makes the fizzy drinks taste good by covering the bitter taste with a sweet flavor so you want to drink it.
Fizzy drinks are usually acidic due to the presence of carbonic acid created by the carbonation process. This acid gives fizzy drinks their tangy taste.
Chewing gum and bubble gum, try to avoid all kinds of sweets, fizzy drinks and very hard things!
Carbon Dioxide makes the drinks fizzy, I also heard that CO2 makes water fizzy with that soda maker thing.
The only bad thing about drinking fizzy drinks like coke is that if the sugary substance is left on your braces it can rust the metal. This means that you have to brush your teeth about 30 minutes afterwards to make sure that this doesn't happen.
Fizzy drinks are not fizzy in space as there is no oxygen to fizz the bubbles. The fizz in fizzy drinks is carbon dioxide coming out. In a vacuum the liquid would "boil" because of the water vapour coming out, and would probably freeze because of all the heat removed with it. Oxygen plays no role in this at all.
