What's going on here? We were both wrong. It looks like the gas ADDS weight. The fizzy soda is a tiny bit heavier! Why did this happen? Ask me, I know!. Try It!: Flat and Fizzy So what do you think about gas now? Oh yeah, adding gas makes things weigh more, just like air. This doesn't make sense. How can a gas have weight?
