It's a gas exploding !!!!

On Thursday the 30th of June we did a science experiment.It was about chemical reaction.
First we put baking soda in a sandwich bag.Then we put vinegar in a plastic cup.We had to place the cup in the bag with the baking soda in.Next we tipped the vinegar into the baking soda .Then we watched it explode.The vinegar dissappeared and it fizzed and foamed up.
