homemade smoking devices

since im cheap and broke ive been resorting to making home made pieces lately. i've made a 4 ft bong out of some graphics tubing, a 3 chamber bong with gatorade bottles, and another bong with gatorade bottles that has 2 bongs that you light simultaneously and then those bongs both go into another chamber, so your pretty much ripping two 2 chamber bongs at once . i'd put up pictures but im lazy as shit too haha.

anyone else have any cool homemade pieces or bongs?
