Charlotte Allen introduces the first of a series of problem-solving programmes.
With limited time and unusual materials, teams from Wilkinson Sword, BXL Plastics and three London immunologists are challenged to design, construct and demonstrate a moving problem with a cracking result. Heinz Wolff, director of the Medical Research Council's Bio-engineering division, is the principal judge and problem-setter throughout the series.
Today's specialist judge is Ian Fells , Professor of Energy Conservation, University of Newcastle.
