What each ingredient does

Lemon juice
Provides sourness and acidity, which reacts with the baking soda to produce the fizz.
Sugar
Adds sweetness that balances the tartness of the lemon juice.
Baking soda
Reacts with the lemon's acid to release carbon dioxide bubbles, creating the effervescence.

The step that matters

Serve immediately after adding the baking soda. The carbon dioxide formed when baking soda meets the lemon's acid escapes as gas quickly, so the fizz fades within minutes. Stir briefly, then serve before the lemonade goes flat.
