The first one is solid
The second one is liquid
The third one is gas
John showed us an experiment with Dr Pepper, Cherry Cola and Fanta to find out which one had the biggest fizz. It was Dr Pepper.
He mixed lemon juice and baking powder and collected the gas in a balloon. This one expanded the most.
Finally we weighed the gas in the balloons. The carbon dioxide balloon was the heaviest. We thought it was 'awesome', 'amazing' and 'super cool'.
