You don't buy much for US$1.5 but I suppose you might buy a small working electric motor and other parts from a scrapyard. You need to support the rod/tube with at least one bearing (probably two, one at each end). Again you may be able to find good ball or roller bearings at a scrapyard. You will need shafts at each end (probably) centred and with assemblies and supports for the bearings. The drive from the motor is probably best accomplished by belt to a pulleys onto one of the bearing shafts. If you get robust bearing and mounts a degree of off centre weighting won't matter at low speeds but you may need to attach some weights to balance the rotating assembly.

cap the ends, drill holes in opposite sides at opposite ends, then pump air or steam into the pipe under pressure. The result should be spin.
