Shaolin 18 Movement staff folds in on itself like 'san cai jian'

I wrote an article along with pictures of all the movements here

Shaolin Eighteen Movement Stick

The beginning of the article relates the opening move to Sun Wukong, the monkey king.

The end of the article has the pictures. This form is the introductory staff set we use.
I have not heard of Fire Water Staff. Is there any info on that?
