>>957772Gyroscopic stems would be difficult for sure, but pipes are plenty lightweight (a few oz at most) and pretty durable anyway.
For just plain knockabout "I don't care if it gets tossed around, dirty or broken because it's cheap anyway" use, it's hard to beat a corncob. That they're god tier smoking pipes is just icing on the cake here-they're $7 and available at any drugstore in the land.
Or, if you need waterproof and easy to clean, an old Venturi or "The Pipe"-like pic related-fills the bill for cheap. Made of plastic with a graphite bowl. They'll never warp, you can clean them with soap and water and they're cheap on eBay. I got this one for $10.
