Merry Christmas Eve, all! I just submitted an idea to the Mythbusters forum, starting with:
There have been several suggestions for Gilligan's Island Myths: mostly about recreating the idiotic contraptions the Professor cooked up. How about the One Big One that he didn't do, namely: Given the contents of a boat similar to the Minnow in the 1960s, and native island materials, is it possible to construct a radio transmitter? Assume the transmitter the ship was provisioned with was totally destroyed.
We'll see if it gets any traction.
God Bless us, every one....
