ABSTRACT:
A kit for visual demonstration of principles relating to carpets and carpet care. The kit includes a horizontal base member, vertical members removably securable in erect position with respect to the base member at their proximal ends, and means on the base member to hold the vertical members in carrying position when not in their erect positions. A highly preferred base member is a transparent rigid box with spaced upper and lower walls, the vertical members being attacked to the lower wall and extending loosely through openings in the upper wall.
The method includes applying dirt onto a shaft near its distal end and, when the shaft is erect on the lower wall of the preferred base member, executing a cleaning step. The cleaning step may involve applying a free liquid, which carries dirt through the opening into the rigid box, or rubbing with a damp wiper and then removing the dirty wiper from a position on top of the rigid box.
