Haven't you ever seen three stage bottle rockets?

No, but I've fired lots and lots of the composite whistlers. They have three "stages"; one burns through, then the next, then the next. Since they don't separate, they aren't really stages. (according to a mythbusters show, anyways).

Sorry,I forgot the /sarcasm after my post.

When I was young we would try to tie bottle rockets together in various ways to create multi stages but it always ended in failure.
