I highly recommend 1, 2 and 3 liter versions made with soda bottles.
Aluminum foil on the outside, water filled, brass knob screwed onto
the cap with a stainless steel chain dipping down into the water.

Charge 'em with a decent Van De Graaff generator and they MAY not be
lethal, but the survivors will definitely have a tale to tell.
Similar to the level of hit described by Ben Franklin when he
intended to electrocute his Thanksgiving Turkey.
