Abstract: A training apparatus for training a child how to blow his or her nose includes a tapered chute having proximal and distal ends. The tapered chute defines an internal passageway connecting the proximal and distal ends. The proximal end includes a proximal opening that is sufficiently wide to fit over a child's nose. The distal end includes a distal opening that is smaller than the proximal opening. The internal passageway includes a narrow portion, adjoining the distal opening, and sized to snugly accommodate a projectile lodged therein. When air is exhaled into the proximal opening, the exhaled air passes through the internal passageway and builds pressure behind the projectile such that the projectile is forcefully ejectable from the distal opening.

Abstract: A holding device. The holding device can hold portable objects such as MP3 players, mobile phones, navigation devices, etc. The holding device has one or more arms, which can grip the portable object. In predetermined orientations, one arm is prevented from moving outward, to prevent the held portable object from falling even when it is being inserted or removed from the holder.
