Nothing beats the joy of balloons at kids' birthdays. As a parent and science enthusiast with years of hands-on experiments, I've found this simple trick using baking soda and vinegar to be a hit – no lungs required!
This classic chemical reaction generates carbon dioxide gas to inflate the balloon right before your eyes. Watch how:

1. Pour about 3 cm of white vinegar into the bottom of the plastic bottle.

2. Using the funnel, fill half the balloon with baking soda.

3. Stretch the balloon's opening over the bottle neck.
4. Carefully lift the balloon so the baking soda drops into the vinegar.

5. Watch the magic! The baking soda reacts with vinegar, producing gas that inflates the balloon instantly.

6. Remove the balloon and tie it off securely.
Voila! You've inflated a balloon using just baking soda and vinegar. Simple, safe, and endlessly entertaining for kids.
Safety note: The gas produced is carbon dioxide – avoid inhaling deeply to prevent headaches.
Perfect for parties, classrooms, or rainy-day fun. Try it today!
