Over the next four hours, take the shortest journey of a lifetime. Travel a mere .02 millimeters floating through 7200 individual sheets of graphene. For reference, that's only 4% of the way through a piece of computer paper. Graphene is a relatively new wonder-material with amazing applications in technology and construction. A semimetal with high electrical and thermal conductivity, graphene is transparent, waterproof, and hundreds of times stronger than steel. Derived from graphite like that found in pencils, graphene consists of two-dimensional sheets of rings of carbon joined in a hexagonal, chicken-wire pattern. The material cracks easily, but holes can self-repair in the presence of available carbon atoms. There is more to learn about graphene on the wonderscience.com blog. Music by Stuart Price.
