The $ (Money) Train is a Hamm’s Water Works innovation, designed and created by C$, Hamm’s former apprentice and longtime collaborator. While not the first dual-chamber and dual percolating piece in the waterworks line, it is my favorite by far! Beyond smooth. Effortless. Those are the first things that come to mind when I think of the incredible smoking experience this piece offers. The design really sets it off though, with it’s locomotive-like appearance and expertly crafted seals on the inventive internally-sealed vertical exo-diffys. Anyone in the market for a great enail piece or daily driver should look no futher!
