reminds me of when I was in 5th form at school (aged 16). We used to stand the first years on a sheet of glass and get them to hold on to the probe of a Van daGraf generator while we wound it up. Their hair would stand up like a David Bowie nightmare.
There's another cool UK youtube channel I stumbled onto about a year back, 'Photonic induction', who has done a number of really neat electrical experiments at crazy voltages!
