Static electricity is a form of electricity that does not circulate: it is electricity at rest. Objects carry positive electric charges when some of their atoms have fewer electrons than they should, and they carry negative electric charges when some of their atoms have more electrons than they should. A simple way to produce static electricity is to rub two objects (made of certain materials) together: this transfers electrons from one element to another, giving each a positive or negative charge. Positively and negatively charged objects are attracted to each other like magnets, because each wants to lose or gain electrons. When static electricity becomes strong enough, so many electrons jump from one thing to another that they cause a visible electrical spark, which you will feel as a small "shock" if one of the things the electrons jump to is you. A Xerox® copier, generically called a photocopier, operates primarily on the principles of static electricity. Electric charges can be positive or negative, which is a bit like the poles of magnets.
