<p>A jumping toy (60) comprising a projectile (10) comprising a cushioned head (16), a propulsion mechanism (30), a base (14), and, in some embodiments, a releasable catch mechanism (20) that prevents the propulsion mechanism (30) from activating until the catch mechanism is released. In various embodiments, the propulsion mechanism (30) may comprise a spring (12) with the cushioned head (64) attached to the spring (12); the base (14) may comprise a launching tube (156) into which the spring (12) is compressed; the toy (60) may comprise an article (152) with a spring (154) mounted in an inner compartment; or the toy may comprise a launching apparatus (600) comprising a projectile interface and a base (606), wherein movement of the projectile interface relative to the base creates stored energy that is subsequently converted to kinetic energy and transferred to the projectile.</p> |
