I was thinking of inventing a pipe that one can smoke while hanging upside down. What do you guys think, is there a market for it? Just kidding, but something like that... certainly would be revolutionary!
Gyro-Pipe!Maybe a bowl with a weight on the bottom, and a ball-bearing ring around the stem. So that no matter what way you leaned the bowl would always be facing up.
Pair a setup like that with one of those weird around-the-neck harmonica rigs, and you may have a perfect pipe for the "Pipe smokers who are into rock climbing" niche.
