Here is a cool thing to do with Buckyballs - build a nanocar!
Only took them 8 years.
Rice scientists build world's first single-molecule car
'Nanocar' with buckyball wheels paves way for other molecular machines
Rice University scientists have constructed the world's smallest car -- a single molecule "nanocar" that contains a chassis, axles and four buckyball wheels.
The "nanocar" is described in a research paper that is available online and due to appear in an upcoming issue of the journal Nano Letters.
The nanocar consists of a chassis and axles made of well-defined organic groups with pivoting suspension and freely rotating axles. The wheels are buckyballs, spheres of pure carbon containing 60 atoms apiece. The entire car measures just 3-4 nanometers across, making it slightly wider than a strand of DNA. A human hair, by comparison, is about 80,000 nanometers in diameter.
