There is a book called TEACHING ABOUT ELECTROSTATICS: AN AAPT/PTRA-PLUS
WORKSHOP MANUAL by Robert Morse, available from AAPT or PTRA for about $10.
The book uses modern disposable stuff (plastic, foil, straws, popcans, styro
cups, etc) to replace Ben Franklin's historic disposable stuff (thread, sealing
wax etc) and replicate many of Franklin's expts for elementary through HS
students.  Students build their own electrometers, indicating electrophorus,
automatic electrophorus (induction machine like a whimhurst generator) etc
for under a dollar.  A nice resource, and Morse presents at AAPTs a lot.

I really like the use of Neon bulbs to determine polarities and indicate
low level electrostatic charges.  Well worth checking out.
