DECORATIVE TOY USING AIR FLOW

PURPOSE:To provide a toy which is safe and produces a visible change abundant in variety by a method wherein a large cylinder is connected to the other end of a clear cylinder having the one end being open through an expansion pipe, a closing plate is mounted to the other end of the large cylinder, and an inflow pipe formed by a flexible material through which fluid can flow toward the closing plate is coupled to the drum part of the large cylinder. CONSTITUTION:A cylinder body 10 has a large pipe 3 connected to the lower end of an erected small pipe 1 through an expansion pipe 2. When fluid is discharged in a large pipe 3 of the cylinder body through a fluid discharge pipe 5 with the aid of a fan 11, a spiral flow is generated in the small pipe 1, and the spiral flow is brought into a fluid state determined by the size and an airflow of the cylinder body. By bringing the fluid discharge pipe 5 into a flexible state and applying one-way throttle on a part of the discharge pipe 5 by means of a pinch member, the revolving component of the spiral flow is extremely reduced. When ball bodies 8 having proper specific gravity and size are charged in the cylinder body 10, the ball bodies 8 perform various movement according to a fluid condition in the small pipe 1. Combination of illumination and a stroboscope of variable cycle causes provision of a subtle and profound aspect.
