To make your own version of Fizzies, the classic effervescent drink tablets that fizz in water and create a soda-like beverage, you can follow a DIY method that combines citric acid, baking soda, flavoring, and sweetener. Here's how you can do it safely at home.
Citric acid – 3 tablespoons (sourness and fizz)
Baking soda (sodium bicarbonate) – 3 tablespoons (fizz)
Powdered drink flavoring – 2–3 tablespoons (e.g., Kool-Aid or natural fruit powder)
Sweetener – to taste (stevia, sucralose, erythritol, or sugar if drying properly)
Cornstarch – 1 tablespoon (optional; helps with stability)
Small amount of water or alcohol (e.g., vodka) – for binding
Bowl for mixing
Mold or ice cube tray
Measuring spoons
Spoon or spatula
Parchment paper or food-safe drying surface
Mix dry ingredients: In a bowl, thoroughly combine the citric acid, baking soda, flavor powder, sweetener, and cornstarch.
Add small amount of binding liquid: Lightly mist or drop in very small amounts of water or alcohol while stirring continuously. You want the mixture to hold together when pressed but not start fizzing.
Tip: Use a spray bottle to avoid activating the fizz.
Press into molds: Pack the mixture firmly into your molds or tray. Press hard so they hold their shape.
Dry thoroughly: Let the tablets air dry for 12–24 hours, or use a dehydrator on the lowest setting. They should be hard and dry before storing.
Store: Keep in an airtight container away from humidity.
Drop 1 tablet into 8–12 oz of cold water. It should fizz and dissolve in about a minute, creating a fun fizzy drink.
You can use fruit juice powder, natural flavor extracts, or vitamin C (ascorbic acid) for variation.
For sweeteners, avoid sugars if you're not fully dehydrating—moisture will cause tablets to degrade.
Alcohol (like vodka) is better than water for binding, as it evaporates quickly and doesn’t trigger the fizz reaction.
