In this, the last programme in the series, the team have their rations cut and are put on the spot: can they use their science skills to put some food on the table? And can they make the soap to wash up afterwards, the toothpaste to clean their teeth and a record player for some after dinner entertainment? Seaweed, tree bark and ground up seashells all play a starring role. But which are foods and which are toiletries?

The team is now settled in on the island and this programme's first challenge is to brighten the place up with a castaway flag, dyed with the natural colours of the island. Again, the island's plants seem a useful resource. But not everyone agrees on the best way to achieve this... Their next challenge is to make a compass. They decide to use electricity to magnetise a needle and use seawater to make the battery to generate the current to do it. The problem? Its never been tried before! Finally, a castaway camera and photograph is required. Taking inspiration from the early work of photographic pioneers like Fox Talbot, the team decides they need light sensitive paper and a makeshift camera. However, things don't quite go to plan.

To cope with life on the island - from mosquitoes to storms - is the challenge. A bacteria-busting cream from the island's plants is needed - and the scientists must prove it works with no animal testing. Growing bacteria from one of the scientist's spit, extracting oils from plants and building a microscope to check on progress, are all part of the test. They also build a weather station to detect storms.

The theme is heat and how to use a variety of scientific methods to measure it, adapt to it, and even to change it. Our scientists struggle with their new environment as they strive to stay cool. We see the team sweat and toil to make a miracle - produce an ice cube for a cool drink in the mid-day sun. By brain power and sheer hard work the main challenge is to transform a tiny region of a desert island into a winter wonderland. To check on the quest for ice, the team also have to make a thermometer. And if they can't keep out of the sun they'll have to keep the sun off their skin by producing some sunscreen.

Not for these scientists the simple expedient of sending a postcard to show where they have been. They have to develop the means to make a permanent record of the island - from the highest peak to the loudest sound. Sound recording involves producing a mechanical design similar to Edison's original recording device and making a loud noise to record. To make the map, the scientists have first to make instruments including a metre stick, protractor and even a telescope before 'measuring' the island and checking on local rock formations and the environment. They must make paper and ink from local, natural ingredients - which includes fashioning a quill pen from a bird's feather. Their efforts are compared with the 'real' map.

Harnessing the energy of the environment and using it to explore the ocean by night is the challenge. To help them the scientists are given an old car battery but it's not as straightforward as it may seem - the battery needs distilled water and recharging before it can be used to power the torch, which they also have to construct. The torch, too, presents a challenge - not least for the need to make waterproof glue to hold it all together.

Finally the scientists need to celebrate their success and how better than with a firework concert. All they need to do is make the fireworks and the musical instruments with which to accompany the firework display. The successful conclusion is spectacular, even if the musicians could use a little more band practice!

The first challenges in this series are heavily focused on the "exploration" theme. Jonathan's challenge is to make a rover; a remote-controlled vehicle that could explore strange new worlds. For Jonathan's ultimate test, we subject his rover to a NASA style experiment in the desert.
Iain and Ellen then have to use their geological and botanical skills to search for water in the desert. Once this is done, Kathy and Mike are going to have to find a way of purifying it to make it safe for drinking - an essential component for any mission into deep space.
Watch the team in action pitting their improvisational science skills against these space related challenges.

In this programme, Kathy and Jonathan have to go one better than the Mars Rover in programme one and design an aerial surveyor that can explore much greater areas by floating above land. They have been given a tiny camera which will record whatever the aerial surveyor sees. They make a solar balloon, heated by the power of the sun.
Mike has a very different challenge. In 1970 the crew of Apollo XIII faced certain death when an accident damaged their oxygen tanks. To survive they had to build a carbon dioxide filter and Mike has to do the same.
Ellen and Iain have to work out the magnitude and where the epicentre of the 1872 Californian earthquake was.

The final set of Rough Science space challenges are all about rockets. Mike, Jonathan and Kathy have to make three different rockets, using water as fuel. They also have to design their rockets to carry a raw egg as a "passenger". Mike takes a chemical approach, using electrolysis to split water into hydrogen and oxygen gases then recombining them to form an explosive mixture. Jonathan, with his physics background builds a steam powered rocket and Kathy, also a physicist decides to use pressurised water. The scientists compete to see who can get to the launch pad first, and whose rocket will be the most effective.
Meanwhile Ellen and Iain have to find a way of putting an egg into each rocket and returning them safely back to earth.
