Mine Hero

Mine Hero is the 14th Episode of the Second Season. It aired December 23, 1965.

Synopsis
The Professor is building a raft with a time-release anchor to get them rescued, and everyone is donating all unnecessary metal to melt down for it. Gilligan, however, refuses to let go of his solid gold lucky charm, but he does succeed in pulling in an old World War Two mine in the lagoon which if accidentally set off will blow up the island.

Trivia

 * The Professor should have more than enough metal including the cannon balls from Plant You Now, Dig You Later, remnants of the satellite from Smile, You're on Mars Camera and the old camera equipment from Castaways Pictures Presents.
 * The Professor's plan to disrupt magnetic waves with radio waves is one of the most far-fetched theories he has made in the series.
 * The Professor claims that any explosion in the lagoon would set off the underground gases on the island and destroy it, but there's actually been several explosions in the lagoon, such as in Forward March, Splashdown and Bang! Bang! Bang!.
