If different brands of soda is shaken will they spew the same amount?

No, I have tried this and sodas like coke spew a lot more then ones like Sprite, all bought at the same time, kept at the same temp. and general conditions. I believe it has to do with the formula and ingredients. Not even the SAME brand of soda will be the same. One of the principles in science and engineering is that nothing is the same at larger scales. Are two loaves of bread the same? No. Are two pieces of pie the same? No. Other than that different sodas have different ages, different formulas, and thus won't be the same. Similar yes..!
