just what is going on in googles london office?

A mysterious 'beam' of static electricity has been caught on camera making a passer-by's hair stand on end.

In the clip, filmed outside Google's headquarters in London, Simon Legrand is shown entering the field of electricity before his hair rises - silhouetted by a nearby street lamp.

As the camera then pans towards the building, a large crack of static electricity is heard before the video cuts out.
