• 1/3 cup baking soda
• 1 cup vinegar
• A balloon
• A plastic bottle
1. First put the vinegar in the bottle.
2. Then put the baking soda in the balloon.
3. Now attach the balloon to the mouth of the bottle, lift the balloon upright so the baking soda falls and causes the reaction.
So what do you observe? The balloon will get inflated. But how does that happen?
The baking soda in the balloon gets mixed with vinegar. Now, when the vinegar (which is an acid) gets mixed with baking soda (which is the base), a gas is produced which is called carbon dioxide (Co2). So this gas i.e. Co2 rises above and inflates the balloon. Interesting!!
