Who knew science could look this magical? The Baking Soda Balloon Experiment is not just educational but also an explosion of color, fun, and curiosity. This simple yet eye-catching activity demonstrates the power of chemical reactions, and it’s a hit for both kids and adults who love hands-on learning with a bit of wonder.


Imagine watching vibrant colors swirl and expand a balloon without a single puff of air from your mouth. This experiment combines art and science in the most satisfying way—perfect for home learning, science fairs, or just a fun afternoon activity.
What Kind of Balloon Should I Use?
While any balloon will work, using clear or lightly tinted balloons lets you see the reaction more vividly. The transparent shell beautifully highlights the colored fizzing magic that builds up inside.
Ingredients for the Baking Soda Balloon Experiment
Baking Soda
The key ingredient that reacts with vinegar to create carbon dioxide, which inflates the balloon.
Vinegar
An acid that starts the fizzy chemical reaction with baking soda. White distilled vinegar works best.
Balloons
They capture the gas formed during the reaction, and the more flexible they are, the better the expansion.
Empty Water Bottle
Acts as the chamber for the reaction. A small plastic bottle is ideal.
Funnel
Makes adding baking soda into the balloon a mess-free task.
Food Coloring (optional)
Adds a fun visual twist, especially if you’re using clear balloons.
How To Make the Baking Soda Balloon Experiment
Step 1: Prep the Balloon
Using a funnel, scoop 2 tablespoons of baking soda into a deflated balloon. Gently shake the balloon to make sure it settles toward the bulb.
Step 2: Add the Vinegar
Pour about 1/2 cup of vinegar into an empty water bottle. Add a drop or two of food coloring for a dramatic effect, if desired.
Step 3: Connect the Balloon
Stretch the balloon’s opening over the bottle mouth carefully, without letting the baking soda spill in just yet. Make sure it’s sealed tight.
Step 4: Let the Magic Happen
Lift the balloon so the baking soda falls into the vinegar. Watch as the fizzy reaction inflates the balloon with colorful swirls.
Step 5: Observe and Learn
Discuss the reaction with kids or note your observations—what worked best? What colors made the most vibrant visuals?

Serving and Storing This Science Fun
This experiment is best enjoyed fresh! Since it involves a chemical reaction, you won’t want to prep it too far in advance. However, the filled balloon will stay inflated for a little while, making it fun to display as a quirky science centerpiece.
