Inflating Balloon without Blowing

Collect an empty plastic bottle, vinegar, baking soda and a balloon. Ask your
friends to inflate the balloon using these things. You can do it by following steps:

Step 1: Put 50 mL vinegar in the empty bottle.

Step 2: Put 5 g baking soda in the balloon.

Step 3: Fix the balloon on the mouth of the bottle, taking
care not to drop baking soda into the bottle.

Step 4: Now straighten the balloon and let the baking soda
and vinegar mix with each other.

Step 5: What happens?

Step 6: A chemical reaction takes place with the release
of a gas.

Step 7: This inflates the balloon.
