  I haven't done this myself, but saw it done:
  At school, people leaned onto or sat on radiators below windows during breaks. Radiators were powered by central heating, hot water circulating through pipes in the building - these things differ across countries.
  You take a capacitor, put its ends into a wall socket so it would get a charge - you had to know which one would work and not explode. Then you have to stick both of the capacitor's ends to a pipe that supplied heat to the radiator people sat on. They would feel the discharge on their asses!

  These pipes had often two scratches on them, each for each of the capacitor's 'legs' - paint removed for better conduction
