Presented by Professor Heinz Wolff Fifth Heat: The Still
Washed up on Northern Irish shores are some unlikely items - three modern refrigerators. What use are they without electricity? The teams find out as they reverse the march of science by turning them into something far more basic: stills to make fresh water from the sea. If they run out of ideas there is always the nearby whiskey distillery to offer inspiration! Guest judge
