Abstract: A blowing device for inflating a balloon has a hollow body having a first end and a second end and including an internal air passage through these ends. The first end is connectable with the mouth of a balloon for air to be blown into the balloon from the second end via the air passage. An air valve in the air passage is operable to block passage of air escaping from inside the balloon in a direction from the first end to the second end. Also included are a light effect generator operated by a battery, and an operating member for turning on and off the light effect generator.

Abstract: A game weapon device has a body, a motion sensor in the body for sensing motion of the body, an emitter in the body for, in response to the motion sensor sensing a swing motion of the body, emitting radiation representing firing of the game weapon device, and a detector for detecting radiation emitted by another game weapon device, representing a hit. An electronic operating circuit in the body controls the game weapon device, and includes a hit register for registering a hit each time the detector detects radiation from another game weapon device.
