Enjoyable propulsion toys can be readily propelled by special magnetic impulse reaction systems. The toys include attractive resilient projectiles which are constructed of foam rubber in order to be safe for children. The projectiles are propelled from base units which contain circuitry for the magnetic impulse reaction systems. Preferably, the circuitry includes a flash tube for emitting a flash of light when the projectile is propelled. Desirably, the circuitry also includes an acoustical generator to generate propulsion sounds when the projectile is propelled. The projectile can be in the form of a: toy rocket, toy airplane, toy glider, toy wheeled vehicle, or toy bullet.

1. A toy comprising:a base unit comprising a seat and defining a cavity providing a propulsion tube-receiving receptacle, an electromagnetic coil annularly surrounding said cavity for emitting a magnetic impulse when energized, a circuit for activating and energizing said coil, and a flash tube connected to said circuit for emitting a flash of light to visually simulate an explosion upon activation of said coil; and a projectile comprising a propulsion device for being electromagnetically propelled by said coil away from said base unit, said propulsion device comprising an elongated propulsion tube for engaging said propulsion tube-receiving receptacle of said base unit, said propulsion tube having opposite ends, a plug for closing one of said ends of said tube, an elastomeric propulsion body secured to said propulsion tube for closing the other end of said tube, said propulsion body having a front head portion with a resilient nose and having a back portion fixedly connected to said tube, said back portion being positioned upon and engaging said seat of said base unit before said propulsion device is propelled, said tube having a hollow interior between said ends, a moveable magnetically attractable metal propellant positioned in the hollow interior of said propulsion tube, said magnetically attractable propellant providing a driver, said driver being propelled from said plug at location rearwardly of said coil, through said coil to said back portion of said propulsion body at a location forwardly of said coil in response to said magnetic impulse of said coil when said coil is energized and said propulsion tube is in said receptacle to transfer kinetic energy from said propellant to said propulsion body in order to propel said projectile away from said base unit.
