Balloon assemblies and valves for balloons have improved inflation capabilities. The inlet ends of the balloon valves are disrupted either with a slit or a portion of material removal to prevent the inlet end from being folded back into the valve passageway during insertion of an inflation probe. With the inlet end slit, the slit portions are readily folded back by the inflation probe, thus preventing potential blockage of the valve inlet.

A confetti launching wand is disclosed in which the wand comprises a relatively short barrel portion which contains the confetti, preferably in the form of a stack or bundle, and the barrel portion is connected to a relatively long handle portion. In some embodiments, the barrel portions may be separable from the handle portion and may be replaced by other barrel portions designed to launch multiple bundles of confetti in different, non-parallel trajectories, and/or the handle and barrel portions may be composed of biodegradable materials such as paper and cardboard. Tapered wands are also disclosed which may be composed of deformable materials such as thin plastic, rubber or plastic foam, or rolled cardboard or paper.
