摘要:
A toy projectile launching device for launching toy projectiles includes a spring shaped as a hollow hemisphere that is capable of being at least partially inverted from a primary normally convex position to a secondary at least partially inverted loaded position. Upon release, the spring snaps back to the primary position, thereby launching the toy projectile.
