Ingredients

• 1 plastic bottle
• Balloons
• 1 teaspoon of baking soda
• 3 tablespoon of vinegar

Preparation

Step 1

Add the baking soda in a balloon using a small funnel. Add vinegar in the bottle. Place the balloon on the bottle and then lift up the balloon letting the powder reach the vinegar. You will see some bubbles forming and the release of dioxide carbon gas.

Vinegar is acid and when it finds the baking soda (sodium bicarbonate), the CO2 is formed.
