3. Reaction Chemistry -Volume Occupied by Air is the total volume of the bottle minus the volume predicted to be taken up by the reactants. Water was added to the reactants to meet predicted volume.

4. Car Design – Reaction Vessel Original design of reaction vessel Original design was to add reactants to either bottle, seal the vessel, mix the reactants, and release the pressure from the nozzle

5. Car Design Continued After redesigning our reaction vessel to function with a propel bottle, we designed a car that had removable axels to try different wheel configurations; this was the test for a rear facing triangle Focused on frame support rather than the weight of the frame

7. Conclusions Due to lack of experimental trials, the car we used in competition was not as calibrated as we had hoped, and given more time, we believe we could have preformed better. Because we were attempting to calibrate our car on the fly, our car was inconsistent between trials as there were too many variables to be taken into account. If we were to redesign our reaction vessel, we would use hose to connect the two bottles to the t-joint, as opposed to inserting the t-joint into the bottles to create a tighter seal, as this was the weak point in our original stuff.
