A book full of simple electrostatic devices is "Electrostatics" by A.D.
Moore published by Doubleday Anchor in 1968. This is a perfect start for a
student interested in electricity. The simplest, loudest, brightest spark
animated device is the Clapper shown in the book on page 104.

One of the most curious electric devices that I know is one of the
simplest and less known: Bennet's doubler:
http://www.coe.ufrj.br/~acmq/bennet.html

It was the first method discovered that produced electricity without
friction, and so is historically important. It's also funny to operate,
as with a simple repetition of movements you quickly (at most 20 cycles)
ends with little sparks to your fingers (with metal plates), and enough
charge to operate simple demonstration devices.

Other similar multipliers are also possible, some quite complicated to
operate, as the one of Pfaff and Svanberg (possibly better for higher
voltage output):
