3 R EACTION C HEMISTRY We used 7g of Baking Soda and 100mL of Vinegar to theoretically produce 2.86 atmospheres of pressure in the 700mL Propel bottle.

4 C AR D ESIGN

5 R ESULTS Trial #Amount of Baking Soda (g)Amount of Vinegar (mL)Distance (ft)

6 R ESULTS

7 C ONCLUSION Our car placed 4 th in our lab class. Overall, the distances the car went were fairly consistent, although they were a few feet short of the goal most of the time. We went through about eight different car designs until we finally had a successful run. At first, we wanted to use a balloon instead of a bottle, but we could not get it to go more than 6 feet. Another issue we faced was with the HCl and Baking Soda reaction, which we could not make consistent. We finally decided to use Baking Soda and Vinegar reaction because we had a better understanding of the chemistry behind it and how much of each chemical to use to attain the right distance with our car.

8 I DEAS FOR N EXT T IME If we were to do this experiment again, we would try to find a balloon large enough to hold a greater amount of gas. The benefits of using a balloon rather than a bottle is that the reaction would not take place within the balloon; the balloon would simply be a means for catching the gas produced from the reaction which would take place in a bottle not attached to the car. This would eliminate spew entirely.
