FIELD: entertaining industry. SUBSTANCE: attraction has vessel with filler, and systems for supplying, discharging and disposal of liquid. Liquid disposal system is adapted for creating down current of water flowing from the top to the bottom and for releasing part of filler pore volume to be filled with air. As a result, liquid is forced into pore volume occupied with air and does not go to the surface. Liquid disposal system is designed for cyclic operation alternately with operation of liquid supplying system and liquid discharge system. During operation of liquid supplying and discharge systems, dense filler is converted into fluidized state filler. Such construction eliminates necessity of strict stabilization of pressure and flow rate in liquid supplying and discharge systems. EFFECT: increased entertaining effect and simplified operation and maintenance of attraction. 3 cl, 3 dwg |
