When talking about the most efficient air bag we are talking about using the least amount of chemicals to make the most carbon dioxide to inflate the bag. We hypothesized that a small amount of sodium bicarbonate with a small amount of acetic acid will create enough carbon dioxide to inflate the bag so Humpty

2 agar plates divided into 4 equal sections were used for this experiment. Each section was labeled with a number from 1-8. 8 Sterile swabs were used‚ 1 for each surface swab. 8 surfaces in my home were then identified that could serve as a fomite and swabbed with a sterile swab that was dipped in distilled water to moisten it. Surface #1 was the garbage disposal in the kitchen sink. It was swabbed
