I recently made this corn cob pipe and i will tell you how i made it. A cut off a piece of a cob and drilled out the pith and put a hole in the side then i put the cob in the oven for an our at 200 degrees to dry out the cob and make it smokeable and hard. But while i was doing that i made the stem. What i did was is i went through my closet and found and old broken airsoft gun (m4) and i took out the barrel. So i went to work and bent the stem over my knee into the shape its in now. The pipe itself is a little over a foot long and because of this it smokes cool as an iceburg.
Nice idea. Glad to know there are people out there with an imagination, unlike the threads i see: "how do i maek a bowllll???!"
