How come there aren’t any tablets to make sparkling drinking water (the Soda Stream way), although there are tablets that can make the it sparkling, i.e. water soluble Vitamin C tablets?

Question

I have really searched all over the internet, it doesn’t exist. I believe I can’t be the first one to think of that trick, so there must be a reason for that. Can anyone illuminate me by explaining like I’m really 5, as I’m a chemistry alien. Thanks!

Unlike soda stream, which forces the CO2 intro the water as a gas, the tablets use chemicals like citric acid and baking soda. On top of the lack of pressure to make the fizz “permanent”, it’s difficult to make the chemical reaction on the tablets flavorless. So it works for a one serving like the vitamin c tablets or the root beer which are also delivering a flavor. Not so great for something like sparkling water that you want to just taste like water with bubbles
