5. Trial 1- spillage of baking soda, not all grams went into the bottle. Trial 8- we had a problem with the cap and bottle Trial Volume of Vinegar (mL) Volume of water (mL)Baking Soda (g)Distance (ft) 1180501215 2190501322 3180501021 418050918 51805065 61805075 718050819 8180508.517 9180508.528 1018050720 Stn Dev3.1602.227.21 Avg181508.917

8.  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.
