The Science Channel here in the states runs a BBC show called http://www.open2.net/science/roughscience/”>”Rough Science” where they throw people on an island and have them complete tasks like building an AM Radio, a Camera, insect repellent as well as figuring out their coordinates, all using stuff they find on the island, mathematics and science. It reminds me of our MakeShift section of the Magazine, which has received some amazing responses so far! Keep them coming!
