Exploding corks

We worked in our groups again and poured vinegar into our bottles. We then made a parcel of baking soda and carried everything outside. After putting on safety glasses, we dropped the parcel of baking soda into the vinegar and quickly pushed the cork into the bottle. Standing well back, we watched the cork explode out of the bottle. Who can remember why this happened?
