Has anyone tested pipes or learned from experience which materials dependably float, or do you just have to float-test each one? I would expect corncob pipes to float, and most briar and other woods like beech, maple, and Mountain Laurel, but I don't really know that. Meerschaum might tend to sink very slowly? Morta I would expect to sink quickly. A Falcon might sink because of the metal. Have you lost a pipe, or rescued a pipe or pipes, enough to know? Any info on this might be useful as spring approaches and people spend more time near the water.
