Calcium Carbonate CaCO 3 (g) Hydrochloric Acid (12.1 M) HCl (mL) Water H 2 O (mL) Pressure of Bottle (atm) Distance (ft) Test Day-different surface

 Performance:  Reasonably consistent  Spewed  Approximately right distance  Re-Design Ideas:  Lighter (weight of car)  No spew (angle of bottle)  Re-work wheel assembly (roll straight & less friction)  Use pure calcium carbonate instead of Crayola chalk
