Details: The scientists' challenge is to equip Kate with everything she'll need when she's lost at sea: They have three days until Kate will be in the water, in the dark and putting their creations to the test.

Our scientists-without-laboratories are back and they're on top of the world! They're based high up in the peaks of Colorado in an old ore-processing mill in the spectacular Rocky Mountains. Their first task will be to make the mill safe and habitable, finding a way to provide power and light using only the natural resources around them. In later episodes they'll be making a fire extinguisher to keep themselves safe and cleaning up the environment after a century of pollution. They'll get to know this peak very well while determining how high it is and how much it weighs. At an altitude of 3000m, they face physical as well as scientific obstacles - it's the highest Rough Science ever!
