In conclusion, we seemed to run our baking soda and vinegar car very effectively. It took us a while to get the car to move, but once we did, it ran quite well. We had one run that was precisely 25 feet. Next time I think I will use a different reaction. One that I found was to use calcium carbonate and a weak acid to create carbon dioxide gas. The calcium carbonate preferably needs to be in either granular or chunks for decreased surface area. That way it does not react all at once. In hindsight, I think we did very well in our final project.
