how to do the experiment of what soda has the most fizz?!

Get several identical clear narrow containers -- clear plastic cups would work well for this.

Write the names of the sodas you will be using on the cups.

Pour an equal amount of several different kinds of soda into them, one type into each cup.

Mark how high the fizz goes on each one.

After you drink all the pop, you'll have empty cups with markings from which to collect your data.

I suggest you include Mountain Dew in the experiment. It has the least fizz of any soda I've poured, even in the diet version, but still tastes just as fizzy as the others.
