Replying to Staircase bong

So this coming vacation I and a few other kids will be crafting a staircase bong in one of our friends house (you know who you are) and we need it to be epic. Already the idea of a staircase-tall bong is pretty good (maybe kind of played, but who actually carries through with it?) but we need more features. were making an ice catcher which will be sick, but any other ideas? I'll post pics when its done and sessioned, but any input would be good. It'll be made of PVC with at least a 20 sack bowl.
