PURPOSE: A method for manufacturing a hose for spraying a bubble is provided to increase the quantity of dissolved oxygen in water by that the sprayed bubble goes up like fog extending the whole surface of water. CONSTITUTION: In the method for manufacturing the hose for spraying the bubble, granular grinded materials(1), pores(2) and a hose(3) are included. Many bubbles are among the granular grinded materials(1) by that granular grinded materials(1) are bonded by a binder. The pores(2) are like a discharging tool of bubbles connecting the inside and outside of the hose(3). The size of granular grinded materials of vulcanized resin is 0.2-1.0mm and the thermoplastic resin mixes the ratio of the weight of 5-25 percent about the granular grinded materials. The mixture is put into an extruding machine in the state of maintaining the mixture with the melting temperature of the binder and is pressed out and thereby the hose(3) is manufactured.
