How to Make Sparkling Water Without a Machine

これさえ読めば安心! How to Make Sparkling Water Without a Machineの活用法をロジカルに解説します。

This isn’t a joke. A tiny pinch of baker’s or champagne yeast can turn plain water into a sparkling sensation. But don’t worry—you aren’t making alcoholic soda (unless you add sugar and wait days). This method creates a gentle, natural fizz in just a few hours.

Here’s the deal: Yeast eats sugar and burps out carbon dioxide. That’s the exact same gas that makes your store-bought sparkly water so crisp. We’re just tricking the yeast into doing it for us, in a bottle, without the $200 machine.

What You’ll Need (The Grocery List of Fizz)

Grab a clean plastic soda bottle (2-liter size works best). You also need a bit of sugar—about half a teaspoon. Then, get a tiny pinch of active dry yeast. That’s it. Oh, and cold water to drink later.

Pro tip: Don't use glass bottles unless you want to create a glass-ceiling-cleaning experiment. Plastic is safe because it bends a little under pressure. Your kitchen ceiling will thank you.
