Inflate a ballon using vinegar and baking soda- No mouth needed

 🔬INTRODUCTION

     This blog was created as part of my STE 262 assignment where we were asked by Dr. Peter Aboyomi Onanuga to create our own blog and choose a science related topic to explain. I decided to demonstrate a simple but exciting project — how to inflate a balloon using vinegar and baking soda. This experiment shows how two common items can react to form a gas that fills a balloon making science fun and easy to understand. 

🧪 MATERIALS NEEDED 

• A small clean empty plastic bottle (like a soft drink bottle)

• 1 Balloon

• 2-3 tablespoons of baking soda 

• About 1/2 cup of Vinegar 

• A funnel (or paper rolled into a cone shape)

• A spoon

 

⚗️INSTRUCTIONS 

1. Pour the vinegar into the bottle using the funnel

2. Put the baking soda into the balloon. You can use the funnel for this too and be careful not to spill.

3. Attach the balloon to the mouth of the bottle but don’t let the baking soda fall in yet.

4. Once the balloon is tightly on the bottle, lift the balloon so the baking soda falls into the vinegar. 

5. Watch the magic happen as the balloon inflates.

🧬WHATS HAPPENING? - THE SCIENCE BEHIND IT

     When baking soda (a base) and vinegar (an acid) mix, they react to form carbon dioxide gas (CO2). This gas builds up and needs to escape so it travels upward and fills the balloon. 

 The chemical reaction is:

NaHCO3 (baking soda) + CH3COOH (vinegar) —> CO2 (gas) + H2O (water) + sodium acetate 

 The carbon dioxide is the same gas we breathe out - and what inflates the balloon. 

🧠WHAT YOU LEARN

• How acids and bases react

• How gases can cause physical changes.

• That science can be done at home with simple tools

SAFETY TIPS

 Even though vinegar and baking soda are common household items and generally safe; 

- Avoid contact with eyes and mouth.

- Perform the experiment on a flat surface to avoid spills.

- If you are a kid ask an adult to help. 

- Clean up after the experiment.

TROUBLESHOOTING TIPS

  If your balloon doesn’t inflate properly try these; 

• Use enough vinegar and baking soda. 

• Make sure the balloon is tightly sealed on the bottles neck.

• Use warm vinegar to speed up the reaction. 

• Check if your baking soda is fresh (old baking soda might loose effectiveness) 

📝CONCLUSION

   This experiment shows how simple materials like vinegar and baking soda can be used to demonstrate a chemical reaction. When combined they produce a carbon dioxide gas which inflates the balloon. It’s an easy and fun way to understand how gas is formed during a reaction. Creating this blog for my STE 262 assignment helped me learn more about science in everyday life and taught me how to present my idea in a creative way.
