发明名称 Water-actuated novelty
摘要 A novelty format in which a compressed dry stored material is expanded by addition of water. It is supported by a telescopic array of rods and a sleeve to limit bending of the wetted material. It can be made to simulate various objects such as a stalk or stem, and may carry greetings which rise with the expansion of the material when the material is wetted with water.
