From Bionic.wikia.com:
The Oscar Goldman doll was one of several large-size action figures relased by Kenner Toys in the late 1970s to tie-in with both The Six Million Dollar Man and The Bionic Woman. The doll came packaged with a briefcase containing several items; if the briefcase was opened incorrectly, however, the briefcase self-destructed, bouncing into the air and the interior changing to appear as if it had been destroyed (though it could easily be reset).
