Baking soda and enzymes for vehicle propulsion?
For a student competition, we developed shoebox-sized vehicles that are powered by a chemical reaction. In one vehicle, the reaction of baking soda and citric acid was used to produce positive pressure. In another vehicle, enzyme-catalyzed absorption of carbon dioxide produces negative pressure. The pressure differences are used with hydraulic cylinders to propel the vehicle. Interested people of all ages can try out the vehicles.
