Examples of static electricity

Clothing - when taking off a jumper you may find that your hair sticks on end. That's because the electrons are transferred from one to the other leaving one positive and one negative. Attraction occurs. Sparks may happen as the charges try to rearrange themselves.
Car shocks - Static charges can build between clothes and a synthetic car seat. Then when you touch the metal door ( in which the charge flows) you can get a shock. Conducting strips hang down off some cars which gives a safe discharge to the earth and stops there from being any danger.
Shocks from door handles work in the same way. If you walk on a nylon carpet with insulating shoes then touch a metal door handle the charge flows and you get a shock.
Balloons stick to walls when they're rubbed against it or against hair because the negative charge on the balloon pushes away the negative charges on the way and attracts the positive charges. This is called induction.
A charged comb can pick up pieces of paper in the same way. The comb can be charged by running it through your hair.
Lightning is caused by a build up of static charge.
