Balloon magic

3rd 4th and 5th classes made a gas out of a bottle vinegar and baking soda.This is how you make it: First get a plastic bottle and put a half a bottle of vinegar into it. Then get a balloon and put baking soda in it. Then tie the ballon on the bottle and then pour the baking soda. The soda interacts with the vinegar and it blows up the balloon!
