Abstract: The disclosed educational devices comprise self-adhering members, to which a pressure sensitive adhesive material is applied, on the outside of at least a portion of each member. In one embodiment, each educational device comprises an elongated stick, rod or tube which is sufficiently rigid to be self-supporting. A knob or body of the adhesive material is mounted on at least one end of such stick or the like. Preferably, knobs of the adhesive material are mounted on both ends. The sticks may be adhered to one another and also to supporting surfaces, to produce letters, symbols, figures, geometric designs, and many types of artistic representations.

The adhesive material comprises microcrystalline wax with mineral oil in the proportion of 2 to 12% mixed with the wax to provide greater tackiness, the wax being of a flexible type with a melting point between 150.degree. and 180.degree. F. and a needle penetration between 20 and 50 when measured at 77.degree. F. in accordance with ASTM Standard No. D1321.
