Abstract: An air blowing device includes a housing, a straightening plate, and a display surface. The housing is formed in a box shape having an internal space, and has an inlet port for sending air into the internal space, an air blowing port for blowing out the air from the internal space, and a squeezing part for narrowing the internal space toward a peripheral edge of the air blowing port. The straightening plate is disposed between the inlet port and the air blowing port. The display surface is positioned inside the internal space, and displays video from the air blowing port toward an outside of the housing.

Abstract: It is determined whether execution is to be carried out in a first mode or in a second mode, according to a user's selection operation. In the first mode, a movement of a player object is controlled according to the user's movement operation, and a movement of a non-player object is automatically controlled. Positions of the player object and the non-player object are changed according to the user's position changing operation such that a relative positional relationship between the player object and the non-player object for use in the second mode is a first positional relationship. In the second mode, movements of the player object and the non-player object are automatically controlled while maintaining the first positional relationship.

Abstract: A hydroponic cultivation apparatus includes: a growth tank in which a plant is grown; an air blower which supplies wind; and an air blowing pipe which guides the wind sent from the air blower to the plant. The air blowing pipe includes a first pipe and a second pipe which extend in the same virtual line, and each of the first pipe and the second pipe is provided with a plurality of air outlet holes in a pipe longitudinal direction and supplies the wind from the air outlet holes to the plant. The air blower supplies the wind such that a direction of the wind inside the first pipe and a direction of the wind inside the second pipe are opposite directions.
