Try reading the intro do the snack for an idea:
A commonly available brand of plastic tape can gain or lose negatively
charged electrons when you stick it to a surface and rip it off. By
suspending pieces of tape from a straw, you can build an electroscope, a
device that detects electrical charge. A plastic comb will enable you to
identify whether the pieces of tape are positively or negatively charged.
