Steel Penetration. El Duco, ca. 1976.
A compact penetration effect in which a steel ball visibly passes through a rod inserted through a brass tube. Despite the rod completely blocking the interior of the tube, the ball repeatedly penetrates it before emerging from the opposite end. At the conclusion, the apparatus may be examined. Constructed with tube, steel ball bearing, and black-and-chrome wand. Complete with the original box and instructions.
Light wear consistent with age and use. The box shows moderate shelf wear and crushing from storage. Apparatus remains in very good working condition.
