What each ingredient does

Carbonate of soda
Reacts with the acid to release carbon dioxide, which makes the water fizz.
Tartaric acid
Reacts with the carbonate to release the gas and gives a sharp, tart taste.
Water
Dissolves the two powders so they can react and release the gas.

The step that matters

Cork the bottle immediately. Corking right away traps the carbon dioxide released when the acid meets the carbonate. Gas escapes from an open liquid, so a delay lets fizz leak out before the bottle is sealed.
