Whats within those two buckets?

Answers:    In all my years of experience, I can confidently advise you that one bucket contains "part of a set A" and the other bucket contains "part B". "Part B" is usually the catalyst.
Each company has their own formula, and the components are not interchangeable.

I muse "part A" is a derivative of Diet Coke, and "part B" is a derivative of Mentos.
