1. A method for training a child how to blow his or her nose, the method comprising:
(a) providing a training apparatus comprising:
(i) a tapered chute having proximal and distal ends, the tapered chute defining an internal passageway connecting the proximal and distal ends,(ii) wherein the proximal end includes a proximal opening that is sufficiently wide to fit over the child's nose, the opening defined by a nosepiece having two lobes adapted to fit around nostrils of the child's nose and by a bridge lobe adapted to fit over a bridge of the child's nose,(iii) wherein the distal end includes a distal opening that is smaller than the proximal opening,(iv) wherein the internal passageway includes a narrow portion, adjoining the distal opening,(v) wherein the internal passageway includes a central portion, adjoining the narrow portion, which is narrower than the narrow portion; (b) inserting, by an adult, a projectile into the distal opening such that it is lodged within the narrow portion, the projectile being sized and dimensioned to correspond to the narrow portion; (c) placing, by the adult, the training apparatus over the child's nose such that the training apparatus fits around the nostrils of the child's nose and over the bridge of the child's nose; (d) inhaling, by the child through his or her nose, air and effecting a pulling force on the projectile, the projectile being prevented from being pulled inward into the child's nose by the central portion; and (e) exhaling, by the child through his or her nose, air and effecting a pushing force on the projectile that ejects the projectile from the training apparatus. |
