Great success! (Borat voice)
I have a few tubes with alot of honey built up and recently ran dry. Just plugging them into my vertically oriented bubbler and gently heating it with a torch gave me huge, smooth ropes. Because the Solo stems are so restricted there's a very good "choke" on it for getting dense, satisfying hits - slightly debilitating, even.
This isn't potentially just for reclaiming - you could just drop a dab of good oil into the crevice of the bowl section when its oriented vertically, then heat carefully with a torch. Kind of like making a ghetto eclipse out of a Solo stem.
