Technology:Rough Science（6）
We are Rough Science. Mission control is an abandoned silver mine on the edge of Death Valley. Here the scientists have basic kit and simple tools， ingenuity they supply themselves. For the final programme，Jonathan， Kathy and Mike have to come up with three different water powered rockets. Each rocket will carry an egg and it's up to Ian and Ellen to bring those eggs safely back to earth. Water is not a conventional rocket fuel; traditionally rockets use something a little more flammable. So how do the scientists turn boring old water into a high powered rocket fuel?
