From project page:
The Challenge: “In one week, can 32 young scientists and designers from China and the UK develop a new type of low-cost scanning probe microscope, powerful enough to study the nano world? And can this device transform science education in Chinese high schools? Tsinghua University, Peking University and University College London team up with the LEGO Foundation to invent, make and market their ideas”
Experts said they couldn't do it… THEY NEARLY DID!
