Ideas?

Im feeling adventurous today. Does anyone have an idea for something to make to smoke out of? I will list what i have already made.

Waterfall bong
Highlighter pipe
Grinder
water bottle bong( also a triple peculation bong)
lightbulb vap

fish tank.....maybe

A Lung........ its kinda like the old school Gravity just instead of water. us a bread bag for suction. if mad good and air tight it can be a heavy hitter. if your alone use a candel to light your self up its a two handed deal to pull the rip.

skeleton..

EDIT: a skull

make a pipe out bamboo!!!

hmm, i think a lung is a good idea and if i had a shoot of bamboo i definitely would make a bamboo pipe
