Yes, this is as awesome as it sounds.
Inman convinced his friend Matt Harding (the guy who dances around the world) to play target practice for science. They got the whole "experiment" on film. Needless to say, Harding dances.
The cannon seems to be a portable tesla coil, so the electricity jumps from the coil to Harding's body, following a path of least resistance. Before the current dissipates in the floor, however, we get an added bonus. In Harding's right hand is a fluorescent bulb which lights up with the current.
