First we got a coca cola bottle and we put a balloon around it and there was baking soda in the balloon and there was vinegar in it. Then we lift the balloon up then lots of bubbles came up. Next they came down then the balloon was ful of air. after the balloon was full of air then then the vinegar was back at the bottom.

Hey Will, I liked your description and diagram of the science experiment we did in class. You really thought about each step in the process. Nice job! :)
