The goal of the experiment is to add enough Sodium Bicarbonate and Acetic Acid to fill up a Ziploc bag with the resulting chemical reaction. Background Information The concept of an airbag is simple: A soft pillow to land against in a crash, but the mechanisms are more technical. In the 1980s, the first commercial airbags appeared in automobiles. The purpose of an airbag is to protect the individuals in the automobile from striking hard interior objects, such as the steering wheel. When there is a collision force equal to running into a brick wall at 10 to 15 miles per hour, a mechanical switch is flipped and the airbag sensors react to this switch by activating the inflation system. The inflation system reacts sodium azide with potassium nitrate to produce nitrogen inflation system....
