What's happening?
When you combine the solid (baking soda) and the liquid (vinegar), the chemical reaction creates a gas called carbon dioxide. Carbon dioxide is invisible, except as the bubbles of gas you may have noticed when the vinegar and baking soda mixture began to fizz. This gas is what made the balloon inflate.
