ABSTRACT:
An elongate message holding device consisting of telescoping conical segments surrounded by a fluid-tight cylindrical housing. An axially, centrally located conical segment is provided with a clasp which can be used to hold a card or note upon which desired information can be placed. At another end of the telescoping segments is provided a fluid input into which a fluid, e.g. air, may be blown to cause the axially located conical segment to advance in the same direction in which the pressurized air is inputted. After the axial located conical segment has advanced to an opposite end of the cylindrical housing, its base will engage an end of the conical segment which concentrically surrounds the axially located segment to advance the next annular segment and to permit the next annular segment to receive fluid input form the fluid input opening from a mouth piece. This process of advance of the conical segments repeats as each successive conical segment reaches the clasp end of the cylindrical device until all concentric cylindrical segments have expanded in the direction of fluid input to create an elongate structure having the general appearance of a pole.
