A slingshot device includes a missile and a launcher for launching the missile, the launcher including a handle adapted to be grasped by a user, an elastic strap for projecting the missile, the elastic strap having a first end connected with the handle and a second free end, a launching wedge affixed to the free end of the strap for releasably coupling the free end of the elastic strap with the missile such that upon drawing the free end back away from the handle and then releasing the free end the missile is accelerated forward and launched beyond the handle, and a somewhat flexible control tube connected to the handle for restraining any uncontrolled whipping about of the elastic strap and essentially precluding travel of the free end of the elastic strap forward beyond the handle, the control tube essentially surrounding at least a portion of the length of the elastic strap so that the elastic strap is retracted within the control tube upon launching of the projectile and is precluded from following the projectile beyond the handle.
