Self inflating balloon experiment

🧪 What you need:
1 balloon
Baking soda (or baking powder)
1 bottle or cylinder (plastic container)
Vinegar

⚙️ Steps:
Put the powder inside the balloon.
Pour some vinegar into the bottle/cylinder.
Carefully stretch the balloon over the opening of the bottle.
Lift the balloon so the powder falls into the liquid.
Watch the balloon inflate on its own 🎉

🔬 What’s happening:
When the powder mixes with vinegar, a reaction produces carbon dioxide (CO₂) gas, which fills and inflates the balloon.
