Researchers at Rice University have published a video in which they demonstrate the self-assembly of carbon nanotubes from a distance using a force field created by a Tesla coil.

The process is about as straightforward as it sounds. Scientists take a pile of carbon nanotubes, pour them into a solution and then blast it with a force field from a Tesla coil. As you’ll see, the tubes almost immediately line up with each other and create their own circuit through a phenomenon they’ve dubbed Teslaphoresis.

Remarkably enough, the idea to add LEDs to the circuit came to adjunct assistant professor of chemistry Paul Cherukuri in a dream. While impressive as-is, the team believes the technology could one day be put to use in other fields.
