Does gas weigh anything?

Class: Miss A Pool - Buttermere Year: 2019 - 2020

The children carried out an investigation to see if carbon dioxide weighed anything. Using 4 different types of fizzy drink, they weighed the drinks, then stirred until they went flat & all the fizz was gone. The children the weighed the drinks again & discovered that they were now lighter. So gas, even though it’s invisible, does weigh something.
