A composition, device, and method for maintenance of railroad wood ties is presented herein. The device comprises a system for simultaneously filling rail spike holes in wood cross ties including a controlled system able to move in the x, y, and z planes. The system includes a product distribution box with multiple valves and dispensing lines for applying an environmentally friendly wood filler composition into multiple rail spike holes simultaneously. The wood filler composition is applicable for filling holes or gaps in wood to stabilize wood structures.

A play compound includes additives, which when viewed with 3D glasses, elicit three-dimensional stereoscopic illusions. To present stereoscopic images, the additives in the play compound are viewed through different polarizing filters of low-cost eyeglasses worn by a viewer. As each filter passes only that light which is similarly polarized and blocks the light polarized in the opposite direction, each eye sees a different image. This is used to produce a three-dimensional effect by projecting the same scene into both eyes but depicted from slightly different perspectives. Multiple persons can view the stereoscopic images at the same time.
