2. Reaction Chemistry
Things We Tried: -Baking Soda and Vinegar -Battery Cells: Copper Sulfide and Zinc Sulfide (using salt bridge and metal strips with alligator clips; could only generate 2 volts and very little amps) -Hydrochloric Acid and Potassium Bicarbonate What We Used: Vinegar and Potassium Bicarbonate CH3COOH + KHCO3

3. Key Design Points: Simple, Lightweight, Balanced

Key Design Points: Simple, Lightweight, Balanced
Secured bottle with duct tape on last trial run to prevent from going crooked.

4. Testing Results Trial KHCO3 Vinegar Distance Traveled 1 11.671 g
130 mL
1 in. 2 g
150 mL
7 ft. 3 g
160 mL
12 ft. 4 g
5 ft. 5 g 6 g
Out of bounds 7 g 8
24.69 g
20 ft.

5. Conclusions Performance: -Made the car move -Inconsistant!!!
-Lots of spew
-Didn’t get to 25 ft.
Re-Design Ideas:
-Secure Bottle,
-Tip Bottle Up (to prevent spew)
Comments:
- wasted too much time on battery cells, had to start over and were limited on time
- Could have had much better results if given an extra day
