The barrel 20 is a cylindrical container with an open front end and a closed bottom surface. Air injection hole 24 is formed on the bottom surface and the water injection hole 23 is formed on the side. Since the air injection hole 24 is formed in the bottom surface, the pressure is uniformly applied from the bottom to the top of the container.

The compressor 30 is a structure for generating high pressure compressed air.

The pressure regulator 31 is connected to the compressor 30 to adjust the pressure of the compressed air flowing out of the compressor 30.

The on-off valve 32 is coupled to the pressure regulator 31 to control the outflow of the compressed air.

The first air supply pipes 33 and 33 transfer the compressed air leaked out through the open / close valve 32 to the air injection hole 24 of the barrel 20.
