Abstract

See full text

An amusement system is provided which gives children an opportunity to acquire a formative artistic sense in a simple and clean manner without soiling their bodies and clothes. The amusement system includes: a playing space (A) defined by a floor (10) and partition plates (20) projecting upright on the floor (10); a plastic member (30a) provided over the floor (10) in the playing space (A); and a plurality of plastic members (30b) stacked one on another in tiers along interior surfaces of the partition plates (20) to a height that players can reach. The plastic members (30a, 30b) are each obtained by filling a gel material as a plastic material (32) into a container bag (31) of a flexible urethane sheet to about one half the volume of the container bag (31), then removing residual air from the container bag (31) by suction and sealing the container bag (31). Slack urethane sheet portions of the container bag (31) are brought into intimate contact with each other by the removal of the air, so that the plastic members (30a, 30b) each have a multiplicity of creases on a surface thereof.
