US Patent 11648448 Magnus effect cylindrical projectile and launcher

The present invention is a toy launcher system. A lightweight projectile has an exterior surface symmetrically disposed about an imaginary longitudinal axis and is generally spool-shaped. The launcher is composed of a shaft to which a flexible curled band is attached. The flexible curled band holds the projectile within its curvature. When the launcher is rotated by a user using a general throwing motion the band uncurls, thereby launching the projectile into flight.
