You can do a similar experiment by using a pop bottle with the vinegar inside. a balloon with thwe baking soda inside it. carefully put the balloon on the bottle. When you tip the balloon up straight the baking soda hits sthe vinegar and blows up the balloon. the gas made by the reaction causes the balloon to expand. very neat.
