Ok, so i heard that a good fix for a burning shisha preventative is:
Take a piece of tin foil and poke holes only on the edge. then take some more tin foil, fold it into rectangular pieces, curve it, and place it on top.

I think this would work well for the kinds of shisha that burn easy (Hookah Freak *ahem*)
