Two characters, a nanotechnologist and a student discuss nanotechnology. But what does 'nano' mean? Student use an interactive simulation to zoom in and explore objects at different scales, down to the size of water molecules. Then, the students must organise some of the objects they have seen in order from smallest to largest. This is part of a larger experience called the Nano Design Lab.
