Mountain

16th November 2005 30 mins Season 6 Episode 3

The Rough Science base this year sits on the slopes of a magnificent mountain: Mount Kendall. And for this week’s challenge the team will have the task of getting to know this peak very well, working out how high it is and how much it weighs. Not just the part we can see sticking up above the Mill, but the root of the mountain, too, right down to the bottom of the Earth's crust. There’s a lot of maths to combine with some canny field geology to pull this one off and Hermione and Ellen pull together a unique blend of botany and geology to try and crack the dimensions Whilst the girls get to grips with the mountain, the boys are tasked with producing a pair of sun glasses to protect Kate from the glare of the Sun. At the altitudes they are working, the Sun is particularly glaring. Mike thinks he can make glass out of sand, but it’ll need Jonathan to build a furnace that can produce temperatures of over 1200oC for hours at a time. It’s not something Jonathan feels confident about, and it takes the whole of the first day to come up with a design for an oven that can get anywhere near those conditions. Even when Mike find a possible source of sand nearby, the prospect of making glass, let alone making sun-glasses still seems remote... Back on the mountain, in a combination of tree line mapping, clay model building, good old geological mapping and weighing their rock samples the girls are close to an answer for the mass of the entire mountain – roots and all. But with all their assumptions, estimates and the general inaccuracies of a flat-out three day attempt to survey an entire mountain how close will they get to the real figure?

Clean

Three challenges down, and by now the team are starting to look a little worse for wear - and to be honest, they’re not smelling great either. So this time their challenge is to get themselves - and their clothes - clean. Jonathan has to build a washing machine from scratch. It’s a task that stretches his ingenuity to the limit. His solution is a toploader made from a bucket, a bicycle wheel, some tennis balls and an old power drill. That turns out to be the easy bit - it's the electronic valves and the control system that really tax his brain cells. Will he have to head off for a launderette after all? Ellen helps him out by going in search of a plant that will provide the washing soap. She finds what she's looking for, yucca, but will the strange looking liquid she gets out of the plant really make clothes cleaner? The rest of the team attempt different ways to reduce body odour. Hermione makes a deodorant out of rocks. Things don't entirely go to plan when she has a nasty surprise with a supposedly heat-proof beaker. Mike sets his sights on stopping sweat by creating the same chemical that's used in most commercial antiperspirants. Using aluminium foil and household bleach he sets to work. But all he seems to succeed in doing is creating some very nasty smells. Lastly, Ellen makes a triple action botanical roll-on using a variety of local plants. The three deodorants are put to the test in an armpit sniff trial with Kate as the sniffer dog. For Kate this could be a particularly rough episode of Rough Science.
